One way to cure thrush in the mouth of an infant is to have the doctor prescribe antifungal medications, according to Mayo Clinic. Both mother and baby may require treatment if the mother is breastfeeding.
Mothers and babies can pass thrush back and forth while breastfeeding, as Mayo Clinic reports. Doctors often prescribe antifungal medication for the infant and an antifungal cream for the breastfeeding mother to apply to her breasts. Pacifiers, bottle nipples and breast pumps also need to be sanitized to prevent fungus growth.
Mothers can help prevent spreading thrush while breastfeeding by using nursing pads, according to Mayo Clinic. Designs with plastic barriers encourage the growth of candida, the fungus that causes thrush, so liner-free pads are recommended. Nursing pads keep the fungus from transferring to the mother's clothes, and nursing bras and non-disposable nursing pads can be washed in hot water and bleach to rid them of candida.
Thrush is very common in infants under 6 months of age, and it sometimes occurs after a baby has been given antibiotics for a bacterial infection, according to KidsHealth. Antibiotics can kill off the bacteria that keeps the body's natural colony of candida in check, resulting in an overgrowth of candida.
