Re: My 4 year old........
Thrush is simply a yeast infection in your mouth. The blanket wouldn't cause the thrush because the yeast live in your digestive tract. Is she on any therapy for it now? You can give her yogurt with active cultures which will help. You can also take her into the Dr where they will use a paint treatment called Gentian Violet. It is actually violet and will stain clothing so be careful with it. They can also give her a prescription for Diflucan or oral Nystatin.
Thrush is painful also and makes the mouth feel raw so she might cut down on eating and drinking until it subsides. Yeast can overgrow anytime the immune system is down so there is really no telling how she got the thrush but it is easily treatable. Good luck
