Constipation when starting solids FAQ

Your baby’s poop will naturally change when their diet changes, including starting solids [1]. Stools will likely become darker in color as well as firmer. You may also see pieces of undigested food in their diaper. 

So how do you know if your baby is constipated? Many parents are surprised to find constipation isn’t really related to how often their baby poops, but rather how easy it is for them to go. Some babies poop once a day and others may go several days without a bowel movement. Typically, breastfed babies go longer between poops than formula-fed babies. 

If you notice a change in your baby’s stooling habits, they might be constipated. According to Nationwide Children’s Hospital [2], signs of constipation may include: 

  • Straining more than usual when trying to poop 

  • Looks painful or difficult to poop 

  • Small, pellet-like poops

  • Fewer stools than their usual pattern

  • Swollen abdomen/belly 

  • Decrease in appetite 

Preventing constipation when starting solids may not be completely possible, but you can help lessen the chances by focusing on fluid, fiber, and movement. 

Being well hydrated (drinking enough fluid) keeps your little one’s stool soft and makes it easier to pass. When starting solids, keep the amount of breastmilk and formula the same, and watch for wet diapers throughout the day. You may also introduce small amounts (about 1 to 2 ounces) of water at meal times. Water should not displace breastmilk or formula as the primary liquid in your baby’s diet. 

Serve your baby foods with fiber often to help make pooping easier. When starting solids incorporate foods with fiber such as whole grains, fruits, and vegetables. Some popular choices include oatmeal, avocado, berries, and sweet potatoes. Foods high in iron are also important when starting solids, but are typically lower in fiber. Be sure to offer a variety of foods to ensure all needs are met!

Physical activity helps to stimulate the bowels and makes pooping easier for babies. Allow your baby plenty of time to wiggle around on a playmat, on an activity table, or bouncer. Encourage them to kick their legs around or help them by gently bicycling their legs. 

Make sure your baby is still receiving enough fluid via breastmilk and/or formula feeds. If they are feeding less with the addition of solid foods, you may want to switch up the time when solid meals are offered or decrease the amount of solid foods offered. Additionally, you may offer small amounts of water at meals to increase fluid intake. 

Offer your baby foods containing fiber with most meals and snacks. These foods include things like oatmeal, whole grain bread, nut butter as well as fruits and vegetables. Be aware of iron-fortified foods such as baby cereal, as iron can cause constipation. 

While all fruits are good sources of fiber and can help aid in relieving your baby’s constipation when starting solids, the “P fruits” can be especially helpful. Pears, prunes, plums, and peaches may help your baby go. 

If possible, increase opportunities for your baby to be active or try a baby massage. The physical movement or touch helps to stimulate the baby's bowels to go to the bathroom. Ideas for physical activity include playing on the floor on a playmat or playing at an activity table. You may also rub their tummy to give a gentle massage or try bicycle legs.

Constipation when starting solids FAQ

Q: Do babies get constipated when starting solids?


Yes, many babies do! Constipation is a common side effect as your baby’s digestive system gets used to solid foods. It should improve over time, but talk with your pediatrician if you have concerns.

Q: How do you stop constipation when starting solids?


Focus on fluid, fiber, and movement. Make sure your baby gets enough to drink via breastmilk and/or formula, offer foods with fiber, such as fruits and vegetables, and allow them time to move around. Some babies also respond well to tummy massages.

Q: How long does constipation last after starting solids?


Most babies show an improvement in constipation after a few weeks or a few months of starting solid foods. It’s not to say they will be constipated this whole time, but rather may experience periods of constipation. Talk with your pediatrician if you feel like your baby’s symptoms are not improving.

Q: Can starting solids too early cause constipation?


It may. Prior to about 6 months of age, your baby’s baby’s digestive system may not be equipped to handle solid foods [3] and therefore constipation may be a side effect. It’s worth noting, many babies experience constipation when starting solids, no matter the age of introduction.

Yes, constipation when starting solids is normal. However, that doesn’t mean every baby will experience it. As the digestive system further develops, constipation should start to improve.
