Constipation in babies

Constipation in babies is very common, affecting up to 40% of infants¹¹ and there are many possible causes. But sometimes there is no obvious reason.

Common causes include:

Changing from breast milk to a milk substitute (infant formula) or cow’s milk¹²
Introducing processed foods³
Fever, diarrhea and vomiting can reduce hydration levels. This can increase the risk of constipation¹²

Spotting the symptoms of constipation. Things to look out for include:

A lack of energy³
Being irritable, angry or unhappy³
Decreased appetite¹¹

These symptoms may disappear immediately after having a bowel movement.¹¹

In much rarer cases, constipation may be caused by a medical condition.³

Remember, it’s not unusual for a breastfed baby to go a week without having a bowel movement.³ And constipation is common if you’re changing to formula or cow’s milk.¹²
