Overview
Colic is when a baby cries a lot but there's no obvious cause. It's a common problem that should get better by around 3 or 4 months of age. But call NHS 111 or see a GP if you're worried.

All babies cry, but your baby may have colic if they cry more than 3 hours a day, 3 days a week for at least 1 week but are otherwise healthy. They may cry more often in the afternoon and evening. It may also be colic if, while they are crying: it's hard to soothe or settle your babythey clench their fiststhey go red in the facethey bring their knees up to their tummy or arch their backtheir tummy rumbles or they're very windy It can start when a baby is a few weeks old. It usually stops by the time they're 3 to 4 months old.
Causes
It's not known exactly what causes some babies to get colic. But it may be because babies find it harder to digest food when they're young. Or they may be crying because they have problems with food allergies, such as acows' milk allergy.
