She'll have a white coating on her tongue, gums, inside her cheeks, and it won't wipe off like milk residue will. You should see a Dr to be sure and if she does they'll prescribe an antifungal like Nystatin and it only has a 50% chance of working. If she does have thrush though, you can get gentian violet at any pharmacy and use it and it works wonderfully. My son had thrush and used two courses of Nystatin and it didn't work. I called the lactation consultant and she told me to use GV. Use a q-tip to swab the entire inside of baby's mouth and if you are bf'ing swab your nipples as well or nurse right after swabbing baby's mouth. I did it once a day for 7 days and no more thrush. I will warn you though, it is messy, it's very dark purple and it stains, my son had a purple chin for a week and my nipples did not look natural. And get new pacis or nipple and sterilize any toys that go in baby's mouth. Good luck!
