toddlers are a viral magnets so the most likely underlying cause for the little fever would be his body fighting off a viral invader. fever is not dangerous and the fact that he has slowed down a bit is probably good for both of you. this is just a guess however since i do not know his medical history or have a way of examining him. most viral infections last a week but the fever stage tends to be 3-4 days only. you do not have to treat a fever but you do have to make sure that you treat the misery. tylenol is fine but don't let the thermometer tell you what to do. let his mood dictate the need for tylenol. if he is doing fine with a minor fever just leave it alone. keep him hydrated and if he is showing any signs of an ear infection. sore throat. etc. you can having him examined by his medical provider. it is okay to wait a few days however to see if his immune system will take care of his illness.
