my daughter is 1.5 months old. she seems to cry a lot during diaper change. we have noticed that she first starts crying all of a sudden even in the middle of playtime and then she poops. she is not constipated and passes stools almost 15-16 times a day (not diarrhea either) the skin around her anal opening becomes red. what should I do? how do I help calm her? at night she becomes almost inconsolable.
