Constipation in Children: A Parent's Guide

Constipation is one of the most common GI complaints in childhood, accounting for about 3–5% of pediatric office visits [1]. Hard, infrequent stools are usually related to diet and habits. Most cases respond to simple changes at home.

What counts as constipation in a child

Stool frequency varies a lot across childhood. A breastfed newborn may stool after every feed or go several days without one — both can be normal. A toddler or older child going three or more days without a bowel movement, especially if stools are hard, pellet-like, or painful to pass, generally fits the Rome IV clinical definition of functional constipation 1.

Pain or crying with passing stool, very large or hard stools, streaks of blood on the outside of a stool (from a small skin tear called a fissure), or a child who is holding back from using the toilet can all be signs of constipation even when frequency looks normal.

Common reasons children get constipated

Diet and fluids are among the most common factors. Not enough fiber — from fruits, vegetables, and whole grains — and not enough water can make stools harder and harder to pass 1.

Toilet training transitions are a very common trigger in toddlers. Starting to hold stool — whether from fear of the toilet, pain from a previous hard stool, or simply not wanting to stop playing — can quickly become a cycle: holding leads to harder stools, which leads to more pain, which leads to more holding 12.

Routine changes — travel, starting school, illness, or dietary changes — can disrupt regular bowel habits in children who are prone to constipation.

Medical causes are less common but worth knowing about. Conditions including thyroid issues, certain neurological differences, or (rarely) structural differences can present as constipation. A pediatric provider can help assess whether further evaluation is needed.

Simple things that often help at home

Increasing fluid intake — particularly water — is a good first step for children old enough to drink water freely. For toddlers and older children, adding more fiber-rich foods (fruits like pears, prunes, and peaches; vegetables; whole-grain options) can help soften stools over time 1.

For toddlers and preschoolers who are toilet training, reducing pressure around toileting and making bathroom time feel calm and unhurried can help break the holding cycle. A small footstool to support the feet while sitting on the toilet helps children achieve a more effective position 2.

Gentle physical activity and consistent daily routines also support regular bowel habits in children.

When to talk to a pediatric provider

If simple home measures have not helped within one to two weeks, or if constipation keeps coming back, a pediatric provider visit is worthwhile. Providers can assess for underlying factors and may recommend additional approaches. Evidence-based first-line treatment for functional constipation includes polyethylene glycol (PEG)-based stool softeners, which are well-studied in children 12. However, the right type and dose depend on the child’s age and clinical picture — this is not a decision to make without provider guidance.

Long-standing constipation — sometimes called functional constipation — can be a more stubborn problem that benefits from a structured treatment plan from a provider rather than home measures alone.

Common questions

Is it normal for a breastfed baby to go several days without a bowel movement?

Yes, this is common and often normal in breastfed infants, especially after the first month or two. Breastmilk is very efficiently absorbed, leaving little waste. As long as the baby is feeding well, gaining weight, and the stool is soft when it does come, this is usually not a concern. When in doubt, a call to the pediatric provider is always a reasonable step.

Can juice help with constipation in toddlers?

Small amounts of certain juices — such as prune or pear juice — are sometimes suggested for toddlers with constipation, as they contain natural sugars that can draw water into the bowel and soften stool [1]. However, juice intake in toddlers should generally be limited, and it is worth checking with a pediatric provider before making it a regular part of the routine.

Why does my infant cry and strain but hasn't had a bowel movement?

In infants, this pattern is sometimes called infant dyschezia — a normal phase where a baby has not yet coordinated the muscles needed to pass stool. It usually resolves on its own. However, if accompanied by a very hard or infrequent stool, a distended belly, or other concerning signs, it is worth mentioning to the pediatric provider.

Is it okay to use a suppository for a constipated toddler?

Suppositories and enemas are sometimes used for constipation in children but are not recommended without guidance from a pediatric provider, particularly in young toddlers [2]. A provider can advise on what is safe and appropriate for the child’s age and situation.

When to get care right away

  • —A newborn who has not passed any stool in the first 24-48 hours of life
  • —Constipation accompanied by vomiting, especially bile-green vomit
  • —A distended, hard, or very tender belly
  • —Blood mixed into the stool (not just on the outside from a small skin tear)
  • —Child is not gaining weight or seems unwell
  • —Constipation in an infant under two months that is not resolving

If a child has a severely distended or hard belly with vomiting, or a newborn has not stooled in the first day or two of life, contact a pediatric provider promptly or go to an emergency room.
