My Son is 27 months old and 2 days ago started crying that his mouth hurt him. Ive continued to check his temperature and its stayed around 98.8 for the last 2 days. He still plays well. about every 6 hours he complains again that his mouth hurts. Ive tried checking inside his mouth, (very hard to do). From what I can get a look at I dont see anything in his throat . He does occasionally say it is his teeth . I have given him equal brand for childrens motrin. He awoke about 30 mins ago with a fever of 99.6. I just gave him more baby motrin. He is asleep again. Sleeping more, but not eating well. (He does go through spurts with eating though).
