My son was out in the sun yesterday. He is 20 months old. He seems to be teething. He has been fighting a high fever- over 104 on and off since last night. We have been giving him ibuprofen and acetaminophen which brings it down for a while and also had him in a Luke warm bath for a while. He does not appear to be burned or sick except moaning/ somewhat inconsolable until the medicine kicks back in when his fever is high. When it is brought down he is playful and acts fine.
