My 3 week old has a diaper rash that I can not get rid of!! I've been to the pediatrician. She recommended hydrocortisone cream and aquaphor over top. I've tried that, triple paste and baking soda in the bath. I think it's come to the point that I need to wake her at night just to change her diaper! Which I hate doing because she luckily sleeps 3-5 hours at a time. What do you all think?
