Constipation in Babies

Constipation is usually defined as hard, dry stools that resemble small pellets and are difficult for your baby to pass. It’s a common concern, but remember: not all babies poo daily, and that doesn’t always mean something is wrong. Some babies go every day, others every few days — both can be completely normal.

Signs that don’t necessarily mean constipation:

  • Infrequent poos (as long as your baby is otherwise well)

  • Straining or grunting while passing a stool

  • Thicker, pastier poo — this is common in formula-fed babies


What Can Affect Bowel Movements?

A number of factors can influence how often and how easily your baby does a poo:

  • Fluid intake and hydration

  • Starting solid foods

  • Your baby’s age (poo changes as they grow)

  • Illness or medications


A Key Tip for Formula-Fed Babies

If your baby is formula fed, one of the first things to check is how their formula is being prepared. It's important to:

  • Use the correct scoop provided with the tin

  • Measure water first, then add the powder

  • Avoid using more powder than recommended, as this can lead to thicker feeds — and contribute to constipation

Incorrect formula mixing is one of the most preventable causes of constipation in bottle-fed babies.


If you’re ever unsure, or if constipation becomes a regular issue, always reach out to your healthcare provider for advice.
