Thrush is a mild yeast infection that can cause white patches inside a baby's mouth. Antibiotics taken by either the baby or the breastfeeding mother can cause thrush. While mild cases of thrush go away on their own, some cases should be treated with antifungal medication.
- Confirm that the baby has thrush
If your baby cries while nursing or sucking on a bottle or pacifier, check inside her mouth for white patches. If your baby has white patches in her mouth, wrap your finger in gauze, and touch one of the patches. If a patch comes off easily, it is probably just milk residue. If the patch doesn't come off, or if it leaves behind a raw or bloody area, your baby probably has thrush.
- Treat with topical antifungal medication
Get a prescription for an antifungal medication such as Nystatin from your pediatrician. Treat the baby with medication for two to 10 days, depending on the severity of the symptoms. If the thrush infection doesn't go away, continue treatment for twice as long as any symptoms last.
- Prevent recurrence of thrush
Babies and breastfeeding mothers can pass thrush infections back and forth to each other. If you are breastfeeding, treat your nipples with the antifungal medication as well. Clean all pacifiers and bottles thoroughly.
