Grabbed this item from the Mayo Clinic website...just for future reference or for any other mothers that want to be better informed on prevention and treatment of yeast related infections. Just means things are out of balance and it can in most cases be rather easily restored.
I use acidophilus (available at any health food store).
Treatments and drugs
By Mayo Clinic staff
The goal of any oral thrush treatment is to stop the rapid spread of the fungus, but the best approach may depend on your age and the cause of the infection.
Treating oral thrush in children
Toddlers with mild oral thrush who are otherwise healthy may need no treatment at all. If the infection develops after a course of antibiotics, your doctor may suggest adding unsweetened yogurt to your child's diet to help restore the natural balance of bacteria. Infants or older children with persistent thrush may need an antifungal medication.
Treating oral thrush in infants and nursing mothers
If you're breast-feeding an infant who has oral thrush, you and your baby will do best if you're both treated. Otherwise, you're likely to pass the infection back and forth. Your doctor may prescribe a mild antifungal medication for your baby and an antifungal cream for your breasts. If your baby uses a pacifier or feeds from a bottle, wash and rinse nipples and pacifiers in a mixture of equal parts of white vinegar and water every day until the thrush clears up.
Treating oral thrush in healthy adults
If you're a healthy adult with oral thrush, you may be able to control the infection by eating unsweetened yogurt or taking acidophilus capsules or liquid. Acidophilus is available in natural food stores and many drugstores. Some brands need to be refrigerated to maintain their potency. Yogurt and acidophilus don't destroy the fungus, but they can help restore the normal bacterial flora in your body. If this isn't effective, your doctor may prescribe an antifungal medication.
