About two weeks ago we switched LO's brand of diaper and it just did not agree w/her and after a week we switched back to pampers last week. Since thursday after her pm poops she gets an outbreak of red little bumps--I change her diaper right away and I've been using Boudreaux's butt paste and usually by the morning they are gone. I'm scratching my head because I have no idea why she keeps breaking out?? Any thoughts?
