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.
An overgrowth of candida albincans---the fungus responsible for yeast infections---can lead to vaginal yeast infections and also thrush in the breastfeeding mother. Found in the vagina, nipples, mouth and baby's diapered area, candida albicans thrives in moist, dark environments. Though candida albicans is always present in the body, illness, pregnancy or antibiotic use can cause an surplus of this yeast. When a nursing mother develops a yeast infection, chances are this infection will be present in other ares of the body, such as the nipples, which can lead to an infection in baby as well.
Try it: You can generally buy these online or at your local pharmacy. Like OTC vaginal yeast infection medications, you simply insert them vaginally, often for 14 days in a row, Dr. Ross says. This “has been an effective alternative to traditional medication,” she adds. However, it’s worth pointing out that these suppositories can irritate your skin.
Over-the-counter antifungal creams, ointments or suppositories (with miconazole or clotrimazole) are the most common ways to treat yeast infections. These can take from 1 to 7 days. Your doctor may also prescribe a single-dose pill with fluconazole (an antifungal medicine) for you to take. If you’re pregnant, it’s safe to use creams or suppositories, but not the fluconazole you take by mouth.
