Many parents think that their baby is experiencing constipation when the frequency of pooing changes. Your baby’s poos should be a smooth, soft sausage like consistency. Some babies can go once a feed, others once every few days – some may only go once a week. Breastfed babies are rarely constipated because break milk is easier to digest than formula. Furthermore, a large amount of time between bowel movements is not necessarily an indication of constipation. The most important sign of constipation in babies is that their poo is separate hard lumps (like nuts) and hard to pass or sausage-shaped but lumpy.
