My poor 12 day old baby is getting a diaper rash becus she shts so much & mommy has to wipe her 😢 now I'm sad becus she hollers wen I change her 😔! I caught it before it got really bad but I see it's gotten red & stuff ! I have tons of Cetaphil baby Diaper Cream ! & everytime I use it after she gets changed she seems calmer ! Any kind of suggestions or anything ? 😢😔😢😔😞.. mommy' s very sad 😞
