We just switched a few days ago from pro advance to pro sensitive (Similac) because on the pro advance his poops were SOO liquidy and literally pooping little bits every 30mins - hour. He seemed fine on it but I was worried he was having diarrhea so we switched to pro sensitive now he only poops ONCE A DAY is that normal???? And it looks like this and it’s always a lot! He does seem a lil more fussy on this but I’m not sure
