I've been wondering how you tell if baby has diarrhea so asked the health visitor yesterday. She showed me a diagram thingy (nice) which showed it should look like porridge. If it looks like gravy it's diarrhea. Based on this I think my DD has it alot of the time. But I'm also wondering if the health visitor is showing me bottle fed poo just as she measures DD against a bottle fed weight chart. If not, and she really does have the runs quite a lot, what does this mean, and what can I do?
