Anyone know what to do for it? This is Delia's first time having it and it's BAD. DH said when she woke up this morning there was no redness. 2nd diaper change - red. We put Desitin on it. I just changed her diaper again (not even 2 hours later) and it almost looks blistered =( I put extra strength Desitin on it this time. Any other tricks? It looks so painful. Her first cold and her first diaper rash at the same time. Poor baby.
