My 23 month old gradson is visting. He has a 101.6 fever but he is not acting sick. Shold I take him to the er?

Not necessarily. Fever is your body's attempt to defend itself against an immune system attack. As long as your child is eating, making urine, looking well and carrying on his normal functions do not worry. On the other hand, if he is lethargic, vomiting, not eating this is the time to bring him to the er.
