probably so. My DS "tip" gets red along w/ cheeks when he's teething = acidic poopie. After bathtime make sure its really dryed off, lather in ointment then diaper. Should be better in a.m.
sounds like yeast diaper rash... DD had once and pedi gave us some little tube of cream and it cleared up in 2-3 days. If it is yeast, normal diaper cream does nothing.
