If you notice that your baby has a white coating on his tongue, it may be just the milk residue. You can wipe it off easily. Make sure that you use a clean damp face cloth or gentle finger toothbrush after feeding. 

Milk residue is very common for newborns. Because babies are not able to produce enough saliva to clean their tongue so milk residue stays there. it should go away for a few days. 

However, if you see any signs of the followings, call your baby's provider or a doctor: 

- White or yellow patches on baby's inside of the cheeks, lips, gums or throat 

- If your baby is crying after breastfeeding or sucking on a pacifier or bottle

If your bab's provider diagnoses thrush, she may prescribe an oral anti fungal medication (often nystatin). It may take two weeks to clear up the infection. 

Can I prevent my baby getting thrush? 

Not always. Some babies are more prone to yeast infections. There are a few things that you can consider of doing to lower the chance of getting thrush: 

- Don't give any antibodies unless it is absolutely necessary.

- Clean the bottle, pacifier and your nipple every time you feed your baby. 

- Let your nipples air dry between feedings. 

- Wash your hands before feeding your baby, especially after feeding and diaper changes.
