Hi, we started my daughter on ready made cow and gate at the hospital and then moved to the powder stuff about a week ago (she is 12 days old) but has progressively got more upset after a feed and looks like shes straining to poop. She only does one poo a day now instead of 2 or 3. Could she be finding the powder harder to digest? Anyone else had this issue? Horrible to watch her uncomfortable and crying 😥
