I don't know if this is the right forum for BM questions, but here it goes! My 4.5 week old has a BM about once a day (used to be every 2-3 days). They are very soft, not even soft, there is no actual consistency to them, more like runny. I was thinking that it couldn't be diarrhea, since it's only once a day. Is this normal poo for babies? She otherwise is gaining, seems happy and healthy, and eats well (3-4 oz every 3 hrs).
