This seems like a real "new mom" question to me, but bare with me: when do you define baby poop as "watery"? We have had some oversupply, hindmilk/foremilk problems, and so I have been watching his poo closely - everything says to be aware of "watery stools"... He's 4 weeks old and exclusively breast fed --- obviously it's going to be wet, he only eats milk! So when does it go from being considered normal (I've read normal poo described as "runny") to watery?? Thanks!
