girls, thank you so much for your input.
SO Yesterday I was about to post telling you all that it was only milk and that I guess I am crazy.
But then this morning I woke up and noticed he has spots all over the insides of his cheeks and lips, as well as his tongue. So I was right...he does have thrush.
I just went and picked up the medicine for it, but I have another question: For those of you whose babies had thrush, how long did it take to clear up?
Thanks!
