So Ds is 3 weeks old and while his poops are getting to be less frequent, they are still very often and very runny. He's had a diaper rash for over a week, and after using two different brands of creams, I'm not sure what to do? Is this common in bf babies? Or is he reacting badly to something I'm eating? My lactation groups meet on Thursday, but I'll def take him in to see his doctor if it's something to be worried about.
