Whether you're nursing, formula feeding, introducing purees, or experimenting with baby-led weaning, this guide has got you covered. So sit back, relax, and get ready to embark on this journey towards better sleep and nutrition for your baby. It's time to set them up for a lifetime of healthy habits!

The Importance of Sleep and Nutrition for Babies

Sleep and nutrition play a vital role in a baby's growth and development. Adequate sleep ensures that your baby's brain and body can rest and recharge, allowing for proper cognitive and physical development. On the other hand, good nutrition provides the necessary nutrients for their growing bodies and supports their overall health.

Sleep is crucial for a baby's brain development. During sleep, their brains consolidate and store information, helping them learn and remember new skills. Lack of sleep can lead to irritability, difficulty concentrating, and delayed development milestones.

Similarly, nutrition is essential for a baby's physical growth and development. Babies need a balanced diet that includes a variety of nutrients such as proteins, carbohydrates, fats, vitamins, and minerals. These nutrients support their immune system, promote healthy bone growth, support brain development, and provide energy for their daily activities.

It's important to note that sleep and nutrition are interconnected. When a baby is well-rested, they are more likely to have a healthy appetite and consume the nutrients they need. Likewise, when a baby is well-nourished, they are more likely to sleep better and wake up feeling refreshed.

Understanding the importance of sleep and nutrition sets the foundation for creating a holistic approach to your baby's well-being. By focusing on both areas, you can ensure that your baby is thriving and reaching their full potential.

Understanding Baby's Sleep Patterns by Age and Stages

Understanding your baby's sleep patterns is key to establishing healthy sleep habits. Babies have different sleep needs compared to adults, and their sleep patterns evolve as they grow. By understanding these patterns, you can create a sleep routine that aligns with your baby's natural sleep cycles

According to Stanford Medicine Children’s Health:

What are the sleep patterns of a newborn?

Newborns generally sleep much of the day and night, waking only for feedings every few hours. Unfortunately, there is no set schedule at first – and many newborns have their days and nights confused, so it can be hard for new parents to predict how long and how often a newborn should sleep. 

Generally, newborns sleep a total of 8-9 hours in the daytime and about 8 hours at night. But because they have a small stomach, they must wake every few hours to eat. Newborns spend a significant amount of time in REM sleep, which is important for their brain development.

According to sleep experts, and our friends at Rested Mama, Happy Baby, here are some key newborn sleep milestones and habits:

  • 0-8 weeks old: 
    • Baby may wake every 2-6 hours at night.
    • Wake times tend to be short.
    • They typically nap 4-6 times per day.
    • Bedtime can be anywhere between 8-11pm.
  • 8-12 weeks old:
    • Babies start to exhibit and experience a peak in their fussiness and crying. 
    • They're ready for bedtime and nap routines as they've begun to develop their sleep patterns and sequences.
    • They start to more commonly sleep longer than 2-hour stretches (yay!). And develop 1 core night stretch of sleep.
    • They nap a little less now, about 4 times per day.
    • They benefit from an earlier bedtime, about 6-8pm. 

When do babies start sleeping through the night?

Most babies don’t start sleeping through the night (6 to 8 hours) until at least 3 months of age. But, like many milestones, this can vary a lot by baby – some don’t sleep through the night until closer to 1 year. 

What are the sleep patterns of a 3-6 month old?

As babies reach 3 to 6 months of age, their sleep patterns start to become more predictable. They begin to develop longer periods of nighttime sleep and shorter daytime naps. At this stage, it's important to establish a bedtime routine to signal to your baby that it's time to sleep.

3-6 months is a key time of development for both cognitive and developmental (rolling, sitting, crawling) skills. And baby starts to sleep through the night with proper weight gain. Naps may transition from 4 to 3 per day. Their wake time doubles by this stage, but there are also two sleep regressions that may occur. 

What are the sleep patterns of a 6-12 month old?

Between 6 to 12 months, babies usually have two naps during the day and a longer stretch of sleep at night. They may still wake up during the night for feeding or comfort, but they should be able to fall back asleep on their own.

Baby has consolidated their sleep for solid naps and their ability to sleep 12 hours through the night becomes more consistent.

Baby may experience another 2 sleep regressions. And 'stranger danger' and separation anxiety are at their peak.

How often will baby wake to eat during the night?

In most cases, babies wake up to eat at least every 3 hours. How often your baby will eat depends on what he or she is being fed and his or her age. Make sure you talk with your pediatrician to figure out if you need to wake your baby for feedings.

Why does my baby’s sleep pattern change?

If your baby has been sleeping consistently, and suddenly is waking more often, there may be a problem. Alternatively, your baby may be going through a growth spurt and need to eat more often, or are simply due to changes in development or because of overstimulation.

By understanding your baby's sleep patterns, you can create a sleep environment and routine that supports their natural sleep cycles. This will make it easier for them to fall asleep, stay asleep, and get the rest they need for optimal growth and development.

What are the Signs of Sleep Readiness?

Some of these cues are more obvious than others (yawn), but it's a good reminder to not overlook the signs your little one is displaying that indicate they may be ready for sleep. These include:

  • Rubbing eyes
  • Looking away
  • Yawning
  • Fussing

Common Sleep Issues in Babies and How Nutrition Can Help

While some babies are naturally good sleepers, others may experience sleep issues that can be distressing for both parents and the baby. Common sleep issues in babies include difficulty falling asleep, frequent night waking, and short naps.

Nutrition can play a role in addressing these sleep issues. Ensuring that your baby is getting the right nutrients at the right times can help regulate their sleep-wake cycle and promote better sleep. Here are some ways nutrition can help with common sleep issues:

  • Balanced meals: Providing balanced meals throughout the day can help stabilize your baby's blood sugar levels. This can prevent energy crashes and promote more consistent sleep patterns.
  • Timing of meals: Paying attention to the timing of your baby's meals can help synchronize their hunger cues with their sleep schedule. For example:
    • Offering a nutritious snack before bedtime can help keep them full and satisfied throughout the night.
    • However, offering a large, high-fiber meal before bedtime could lead some digestion discomfort or a late-night BM (and diaper change)
  • Avoiding stimulating foods: Some foods, such as those high in sugar or any amount of caffeine, can interfere with your baby's sleep. Limiting their intake of these stimulating foods can help promote better sleep.
    • Babies should not consume any caffeine.
    • According to the 2020 Dietary Guidelines, babies should not consumer fruit juice, sweetened beverages, or added sugar of any kind.
    • Limiting high-sugar, fruit-heavy meals/snacks before bedtime is recommended.
  • Identifying food sensitivities: Some babies may have food sensitivities or allergies that can disrupt their sleep. If you suspect that your baby is reacting to a particular food, consult with a pediatrician or a registered dietitian to identify and eliminate potential triggers.

            By addressing these nutrition-related factors, you can help improve your baby's sleep and create a more peaceful bedtime routine. Remember to consult with your healthcare provider for personalized advice based on your baby's specific needs.

            Introducing Solid Foods to Babies: Tips & Tricks

            Introducing solid foods to your baby is an exciting milestone, but it can also be a source of confusion and concern for many parents. When to start, what foods to offer, and how to ensure a smooth transition are common questions that arise during this stage. Here are some great tips, tricks, and science-based recommendations:

            • When starting solids, begin with purees or mashed foods to help your baby adjust to new tastes and textures. Gradually introduce a variety of fruits, vegetables, grains, and proteins to ensure that your baby receives a wide range of nutrients.
            • Remember to introduce allergenic foods, such as peanuts and eggs, early and regularly, as this can help reduce the risk of allergies.  Please consult with your pediatrician if you have a family history of food allergies or if you are unsure about introducing certain foods.
            • You can start with single-ingredient purees or combinations. It’s most important to introduce one potential allergen at a time (ie peanuts, tree nuts, egg, soy, wheat, milk, fish, shellfish, soy, sesame) and wait 1 day in-between to watch for a reaction.  Because variety and early exposure is key, you may not want to wait 3-4 days in between every new food as it would take months to expose them to the variety they need.
            • It's also important to pay attention to your baby's cues during feeding. They will let you know when they are full or not interested in a particular food. It's normal for babies to take time to accept new foods, so be patient and continue offering a variety of options.

            By introducing solids in a gradual and mindful manner, you can ensure that your baby receives the nutrients they need while also promoting their interest in different foods. This lays the foundation for a healthy relationship with food and sets them up for a lifetime of nutritious eating habits.

            Nutritional Requirements for Babies at Different Stages

            As your baby grows, their nutritional needs evolve. Understanding these needs at each stage can help you provide the right foods and nutrients to support their development. Here's a breakdown of the nutritional requirements for babies at different stages:

            Nutrition for Baby at 0-6 months

            During the first 6 months of life, breastmilk or formula provides all the necessary nutrients for your baby. 

            Breast milk is the ideal source of nutrition for various reasons including:

            • It contains the perfect balance of proteins, fats, and carbohydrates — as well as essential vitamins and minerals that are best for baby’s brain growth and nervous system development. 
            • It’s also easier to digest and gentle on baby’s developing GI tract.  
            • Nutrients in breastmilk are absorbed better by baby’s body.
            • Breastmilk has disease-fighting factors that may help prevent infections or make infections less severe.
            • Breastfed babies have fewer digestive, lung, and ear infections.
            • Breastfeeding is linked to a lower risk of asthma and skin problems related to allergies as well as a decreased risk of developing a milk allergy.
            • Breastfed babies experience less diarrhea and a decreased risk of some digestive conditions.

            If you are unable to breastfeed, please feel confident knowing infant formula is a suitable alternative. It is designed to mimic the composition of breast milk and meets your baby's nutritional needs. Consult with your pediatrician to choose the right formula for your baby.

            Additionally, 4-6 months is a critical window for early allergen introduction. You may do so with allergen powders added to breastmilk/formula or, as your baby is ready, small tastes of allergen purees.  Read more about introducing allergens to prevent food allergies.

            Nutrition for Baby at 6-8 months

            The American Academy of Pediatrics recommends introducing solids around 6 months of age, when your baby shows signs of readiness. 

            Is My Baby Ready for Solids?

            Here are some general milestones and cues that indicate your baby is ready to start solids:

            • Sitting up with minimal support for the duration of a meal (about 15 minutes)
            • Baby has doubled their birth weight.
            • They have good head and neck control and are able to turn their head away if they don’t want to eat.
            • They show interest in food and open their mouth when food is offered.
            • Baby can pick up objects and bring to mouth.
            • Baby is able to move food from the front of the mouth to the back for swallowing (lost tongue thrust reflux)
            • They’re about 6 months of age.

            Starting Solids: Which Foods Do I Introduce First?

            First off, there is no “perfect order” to introduce foods. The Academy of Pediatrics stresses the importance of offering a variety of textures and foods, especially fruits, veggies, and pureed meats to help baby develop their palate, be exposed to allergens early, get essential nutrients, and learn to love a variety of foods.

            We recommend trying purees that are easy on their young tummy and high in nutrients. For example, carrots, sweet potatoes, squash, green beans, banana, avocado, mango, peaches, and even pureed meat or poultry are all great options to start with.

            Sweet Potato Ingredients

            Kabocha squash found in Almond Butter & Banana, and sweet potatoes, found in Harvest Feast are perfect for baby's first bites and also a rich source of vitamin A, fiber, and flavonoids like beta-carotene.

            Around 6 months of age:

            • Your baby will start with bites and small portions. This is perfect! Remember, exposure and trial is most important during these early feeding weeks. Focus on palate development and exposing baby to a variety of foods, flavors, and textures.
            • Your baby's iron stores start to deplete, and they may require additional sources of iron. Iron-rich foods, such as meat, poultry, fortified cereals, and legumes, should be introduced to meet their iron needs. Alongside iron, include a source of vitamin C to enhance iron absorption. Fruits and vegetables like oranges, strawberries, and broccoli are excellent sources of vitamin C.
            • It's important to continue breastfeeding or providing formula alongside solid foods to ensure that your baby is getting all the necessary nutrients. Breastmilk or formula should still be the main source of nutrition, with solid foods complementing their diet.
            • 4-7 months, baby's are most susceptible to new foods.  So, offering a variety of foods, textures, and flavors is especially important!
            • Exposure to allergens early (4-6 months) and often (several times per week) is generally recommended to help prevent food allergies. Speak to your pediatrician or allergist about your baby's readiness.

            Between 6-8 months, baby is gradually ready for about 2 meals a day – generally about 4 oz (or ½ cup) each.  This is why we developed the Square Meal System in which 2 Square Baby meals per day have been designed to offer 100% of baby’s daily recommended servings of veggies, fruit, whole grains, and protein.

            Nutrition for Baby at 8-12 Months

            Stay focused on variety and balance. For an 8-12 month old, 3 Square Baby Meals conveniently per day offers 100% of baby’s daily recommended nutrition. At this stage, baby is able to tolerate a variety of foods including beans, cruciferous veggies, whole grains, etc.  Be sure to listen to your baby’s cue as you increase solids or introduce new foods. Watch for digestion discomfort or any reactions and note the food, quantity, time, and any other contributing factors in a food journal.

            Continued exposure to allergens is key!


            Nutrition for Baby 12 Months and Beyond

            After 12 months, your baby's diet should include a wide variety of foods from all food groups. And a variety of textures, table and finger foods, etc. 

            Continue to offer breastmilk or iron-fortified formula until your baby is 1 year old. After 1 year, you can transition to whole milk, but consult with your pediatrician to ensure a smooth transition.

            It's important to be aware of potential choking hazards and avoid foods that may pose a risk. Foods like nuts, popcorn, and hard candies should be avoided until your child is old enough to handle them safely.

            By understanding the nutritional requirements at each stage, you can ensure that your baby is getting the right nutrients to support their growth, development, and overall well-being.

            Creating a Healthy Meal Plan for Your Baby

            Creating a healthy meal plan for your baby doesn't have to be overwhelming. With a little planning and creativity, you can provide nutritious and delicious meals that meet their growing needs. Here are some tips to help you create a healthy meal plan for your baby:

            • Variety is key: Offer a wide variety of fruits, vegetables, grains, proteins, and healthy fats to ensure that your baby receives a range of nutrients. Experiment with different flavors and textures to expand their palate.
            • Include all Food Groups: Each meal should include foods from all food groups to ensure a balanced diet. For example, a meal could include mashed sweet potatoes (vegetables), pureed chicken (proteins), and a side of mashed bananas (fruits).
            • Homemade vs. Store-Bought vs Fresh/Delivered: Homemade baby food allows you to have control over the ingredients and flavors, but can be time-intensive. Alternatively, store-bought and fresh/frozen delivered baby food can be convenient when you're short on time.
            Choose options that are:
                • Organic and non-GMO
                • Tested for heavy metals -- and win the Clean Label Project "Purity Award"
                • Nutritionally balanced with veggies, fruit, whole grains, proteins, healthy fats
                • Veggie-forward – and low in total sugar (<7g per 4 oz is ideal)
                • Have no added sugar, and free of preservatives & additives
                • Foster palate development -- offer a variety of herbs, spices, and flavors to encourage a healthy love of all foods
                • Ideally packaged in Sustainable Packaging
              • Prep in Advance: Set aside some time each week to prepare or purchase baby meals in advance. You can batch cook and freeze portions for future use. Or purchase meals to have on-hand so you’re ready when your baby is hungry. This will greatly save time, reduce stress in the moment, and ensure that you always have nutritious meals on hand.
              • Follow your Baby's Cues: Pay attention to your baby's hunger and fullness cues during meals. Don't force them to finish a meal if they are not interested or full. Trust their appetite and let them guide their own eating.

              Remember that each baby is unique, and what works for one may not work for another. Be flexible and adaptable in your meal planning, and don't be discouraged if your baby refuses certain foods. It may take several attempts before they develop a taste for certain flavors.


              Foods that Promote Better Sleep in Babies

              Certain foods contain nutrients and compounds that can promote better sleep in babies. Including these foods in your baby's diet can help support their sleep patterns and promote a more restful night's sleep. Here are some foods that promote better sleep in babies:

              1. Oats: Oats are a great source of complex carbohydrates, which can help regulate blood sugar levels and promote sustained energy throughout the night. They also contain melatonin, a hormone that regulates sleep.
              2. Bananas: Bananas are a good source of magnesium and potassium, which help relax muscles and promote a sense of calmness. They also contain tryptophan, an amino acid that can aid in the production of serotonin and melatonin, hormones that regulate sleep.
              3. Cherries: Cherries are a natural source of melatonin, making them a great bedtime snack. You can offer cherries as a puree or incorporate them into homemade oatmeal or yogurt.
              4. Yogurt: Yogurt is a good source of calcium and magnesium, which can help relax muscles and promote a sense of calmness. Choose plain, unsweetened yogurt to avoid added sugars.
              5. Sweet Potatoes: Sweet potatoes are rich in potassium, magnesium, and Vitamin B6, which can help promote relaxation and sleep. They can be mashed or pureed for easy consumption.
              6. Salmon: Salmon is an excellent source of omega-3 fatty acids, which have been linked to improved sleep quality. Introduce cooked and flaked salmon into your baby's diet to provide these beneficial fats.

                          Remember to introduce new allergen one at a time, waiting a few days before introducing another, to monitor for any potential allergic reactions. As always, consult with your healthcare provider before making any significant changes to your baby's diet.


                          Establishing a Bedtime Routine for Better Sleep

                          A bedtime routine is a series of consistent activities that signal to your baby that it's time to wind down and prepare for sleep. Establishing a bedtime routine can help your baby relax, feel secure, and transition to sleep more easily. Here are some tips for creating a bedtime routine:

                          1. Consistency is Key: Establish a consistent bedtime and follow the same routine every night. Consistency helps signal to your baby's body that it's time to sleep, making it easier for them to fall asleep and stay asleep.
                          2. Start Winding Down: Begin your bedtime routine about 30 minutes to 1 hour before your baby's desired sleep time. This allows them to gradually transition from playtime to sleep time. Activities such as a warm bath, gentle massage, or quiet play can help calm your baby.
                          3. Create a Calm Environment: Make the sleep environment conducive to relaxation. Dim the lights, lower the noise level, and maintain a comfortable temperature. Use white noise or soft music to create a soothing atmosphere.
                          4. Read a Bedtime Story: Reading a bedtime story can be a relaxing and comforting activity for your baby. Choose age-appropriate books with soothing tones and gentle illustrations.
                          5. Offer Comfort: Provide comfort and reassurance to your baby before putting them to bed. This could involve cuddling, singing a lullaby, or gentle rocking. Find what works best for your baby and incorporate it into your routine.

                                  By establishing a consistent and soothing bedtime routine, you can help your baby transition to sleep more easily and promote a more restful night's sleep.
