What should I know about constipation in babies and toddlers

  • Know the symptoms of constipation

  • Understand why constipation happens at these ages

  • Learn common dietary treatments for constipation

While constipation in children is defined as having fewer than two bowel movements per week and/or difficulty passing stools that are small, hard and dry – every child’s stooling pattern is different.1

Pay attention to whatever seems regular for your little one, because any deviation from your child’s “normal” may be unpleasant and leave you both feeling uncertain about what to do next.

What causes constipation?

Often, inadequate hydration is the likely constipation culprit, along with eating a diet low in fiber.

It is important for babies and toddlers to drink enough fluids to keep their bodies properly hydrated and bowels moving regularly.2 And when increasing the amount of fiber in your child’s diet, it is important to keep increasing the amount of water to help process the added fiber.

Is my infant constipated?

Healthy babies under 6 months are unlikely to experience constipation because they receive adequate hydration and nutrients from breastmilk, formula, or a combination.

Remember that it’s very common for your baby to grunt, strain, and turn red while passing stool since their abdominal muscles are still weak so they must work harder to have a bowel movement.13,14

As they become older and their muscles get stronger, they’ll be able to pass stool much easier!

Reasons infants may become constipated:
  • Incorrect preparation of formula. Always make sure to add water first, then the formula powder after so that baby is getting enough fluids and to ensure the formula is not concentrated.15

  • Intolerance or allergy. Certain proteins in formula may cause constipation if your baby is not tolerating them well. And while rare, a breastfed baby may experience constipation if allergic to some of the foods mom is eating.3,4

  • Starting solid foods.

Contrary to popular belief, recent studies have found that formulas with iron do not necessarily cause more constipation than formulas without iron.5,6

What are the signs of infant constipation?
  • Excessive fussiness

  • Spitting up more than usual

  • Unusually hard stools, sometimes with blood

  • Straining for more than 10 minutes without passing stool

  • Having considerably fewer bowel movements than normal7

Will starting solids cause constipation?

Firmer, less regular bowel movements are common once your little one starts solid foods (usually around 6 months).

This is because the digestive track needs time to adapt to digesting.13 Think about it this way: solid foods in equals more solid poops out!

Your child’s normal stooling will change from being softer from an all liquid diet to it becoming firmer and less frequent.16 Note that some straining during bowel movements is normal, as babies still have weak abdominal muscles.

Tips to help your infant with constipation

Always reach out to your child’s healthcare provider if a change in your little one’s stool habits is concerning.


When preparing formula, add water first and then the powder to ensure baby is getting enough fluids.15 If constipation is consistent even with correct preparation of formula, speak with the pediatrician about additional signs that your little one may not be tolerating the formula well.

Even though research indicates that iron in formula may not cause constipation, all babies are different. If you feel this is the cause, call the pediatrician before switching to a low -iron formula, as iron is important for growth and development.

Ask the healthcare provider about trying a bit of juice

If constipation does not improve, a small amount of 100% prune, apple, or pear juice may be added to formula or breastmilk as long as baby is older than 4 weeks.7 The type of sugars in these juices pull water into the intestines, helping baby pass stool.

This technique should only be used cautiously, and only a small amount of juice is needed. Always contact baby’s pediatrician before trying it and to learn the amount they recommend using.

Note that juice is not recommended for infants younger than 1 year old at any other time.

If these dietary changes do not work, or if you are at all concerned, call the pediatrician.

Is my toddler constipated?

Once in toddlerhood, constipation can occur if your child holds in his stools. The longer the stool stays in the colon, the harder it becomes since the body continues to absorb fluids from it. As more stool gets backed up, the colon stretches, making it more difficult for the colon to then push the stool out.

Some children delay passing stool because they don’t want to stop playing, others feel embarrassment or stress about using the bathroom, while sometimes stool-withholding stems from fear of a painful bowel movement.1

What are the signs of toddler constipation?
  • Dry, hard stools with pain upon passing

  • Blood streaks along the outside of the stool

  • Abdominal pain with hard and infrequent stools

  • Swollen or bloated abdominal

  • Pellet sized stools passed with straining or grunting

  • Standing on tiptoes and rocking back and forth

  • Clenching buttocks muscles

  • Making dancelike movements

  • Stool or urine in underwear1

Although constipation is more common in toddlers than babies, most cases aren’t serious and generally last a short amount of time. Even though most cases aren’t dangerous, it is important not to ignore symptoms or leave constipation untreated because it can lead to more serious health problems.

Tips for Toddlers with constipation

Keep your child hydrated

Keeping your child well hydrated will help alleviate and prevent constipation. Choose water as the main source of hydration and limit drinks such as fruit juices (and no juice under the age of 1).

And remember that in addition to fluids, fresh fruits and vegetables can also contribute to proper hydration.

Include lots of fiber in your child’s diet

The recommended amount of fiber for toddlers (children 1-3 years old) is about 14 grams of fiber per day.8

Include vegetables, fruits, beans, and whole grains in your child's diet to help meet this goal. Aim to provide a vegetable along with whole fiber-containing grains at each meal, a fruit with each snack, plus beans a couple times per week.

Examples of foods with fiber include:

  • Apples and pears (keep the skin on for added fiber), berries, prunes

  • Sweet potatoes, peas, broccoli, beans

  • Oatmeal and whole grain bread or pasta.

You can’t go wrong with vegetables and fruits so offer a variety daily.

Fiber amounts in foods

For reference, half a cup of cooked beans has about 6-9 grams of fiber, 1 small apple with skin has about 3 grams of fiber and half a cup of broccoli or greens has about 3 grams of fiber.

Check the nutrition facts panel on whole grains to determine the amount of fiber they provide.

Avoid too many low fiber foods

Examples of foods that are either low in or don’t have any fiber include cheese, chips, ice cream, white breads, and refined grains (such as white rice), and many processed foods.

Try swapping out low fiber foods for those high in fiber.

Will probiotics help?

Probiotics are beneficial bacteria in foods that can help promote our health in different ways by colonizing in our gut. While current research is not firm on whether probiotics may help alleviate constipation, results are starting to look promising.10,11

Chat with your child’s healthcare provider about introducing probiotic-rich foods into your child diet.

Encourage your child to move their bowels

When potty training, ask your child frequently if they need to use the bathroom and visit the bathroom regularly even if your child does not ask to go. Help your child feel comfortable using the bathroom in places other than your own home.

If constipation persists, contact your healthcare provider

If your child is experiencing persistent constipation for 2 weeks, or constipation accompanied by fever, vomiting, blood in stool, swollen abdomen, or weight loss you should contact your child’s pediatrician.

Do not use treatments such as mineral oil, stimulant laxatives, or enemas without consulting your child’s pediatrician.
