my 2 year daughter has sores in her mouth, 1 is on her palate around her front 2 teeth and the other is near the tip of her tongue, she does have a dummy but I find it highly unlikely this to be the cause, as it appears to be very painful for her when eating and drinking.  The sores have appeared a couple of days after she spent 2 days with a high fever.  Please do you have any idea what this could be.
