Q: My baby has a terrible case of diaper rash -- it's bright red with blisters. What should I do?
A: It sounds like your baby may have a yeast infection diaper rash, which can happen if a mild diaper rash gets infected with yeast. This is especially likely if your baby recently took antibiotics. If your baby's had the rash for more than a few days and go-to diaper rash treatments (like Desitin or A+D ointment) haven't helped clear it, call your pediatrician. You'll probably need an anti-fungal cream (there are over-the-counter and prescription versions, but you shouldn't use them without your doctor's approval), which usually helps beat the rash quickly. Your baby should also be evaluated to make sure it isn't something more aggressive than diaper rash.
While your baby is healing, don't use baby wipes or any perfumed soap or bubble bath (which you should be avoiding anyway). Instead, try a soothing oatmeal bath, which can help alleviate the itch. After the bath, let her bottom air-dry before you dress her in a clean diaper. It's also important to keep your hands and your baby's hands clean after diaper changes, since yeast can spread to other areas. If you don't see any improvement in the rash within three to five days of treatment, or your baby develops a fever or seems lethargic, give your pediatrician a call.
