My 4 month old niece has had infrequent bowel movements since birth, and was a poor feeder. She didn't poo for more than a week when she came home from hospital and has always had a huge belly out of proportion to her general size. She is formula fed and at first only pooed once a week, now twice a week ( explosively!). My poor mother ( retired nurse)is really worried that the baby has Hirschsprung's disease but doesn't want to panic the parents unnecessarly by suggesting they go to the doctor. I am trying to decide whether to talk to my brother.
Any parents with experience out there?
