THIS WORKS GREAT!!
I had that too. I treated it as a yeast infection and it's easy to get rid of. Go to a health food store and buy Maxi Baby-dophilus. It's a powdered pro-biotic (good bacteria). Put it on your nipple before you breastfeed-it's good for the baby too and will keep the yeast away in his mouth. You can even put some on his tongue to keep him healthy, that's what its for. Do that a few times and it will go away if it's a yeast infection.
