Grandson had hand, fooot and mouth disease about 2 weeks ago, better, had 1 year old check up and got flu shot yesterday, but had a bit of a cold. Last night my daughter gave him a litttle bit of a whole wheat waffle and this morning his lips were swollen, as she was giving him some Benadryl she noticed inside his mouth was white. Benadryl seems to be helping and lips look a little better and he seems to be acting ok. What about the white inside the mouth? Thank You.
Hello, There are a couple possibilities.  The white area inside his mouth could be a common yeast infection called thrush, which can be treated with Chat Doctor.  It should look like pieces of lace stuck on the inside skin of his cheeks, tongue, or gums.  It could also be a healing sore from hand, foot and mouth infection.  Most sores or cuts or bites inside the mouth go through a healing process with some pink/redness, then a white membrane or white looking skin, then back to normal shiny pink mouth lining. Nothing has to be done for this.  More concerning is the swollen lips.  If this has not resolved, or your grandson has hives on his body, your daughter should call her pediatrician. Hope I have answered your query. Let me know if I can assist you further. Take care
