DS2 is 9 days old. He's on soy formula. He's had liquid poop for about 5 days. We've talked to our ped and he isn't concerned at all. Well last night he probably had 9-11 poopy diapers and they are pure liquid.

Right now his little butt is red and looks like a burn. It has to be painful, when we clean him off he screams. We've tried aquaphor and now we are trying desitin but we can not seem to keep up.

Any tips? Or advice?
