How do you know the difference between diarhea and a normal poop if you EBF? DS's poops were usually very runny but now that I have introduced cereal it is getting a little more solidifed. Sorry TMI! Anyway, he has a cough and is a little irritable. He is definitely getting sick. His poop was like water and I am trying to determine if it is diarhea or normal (he didn't have cereal last night). No fever just a cough! Thanks!
