My son will be 3 in a couple of weeks, and he's been crying all day. I thought he was just upset because everyone was holding his new little sister and not him, but I just got home and realized how warm he is. He's asleep now, just took his temp and it's at 101.7. Is that a high fever for his age? He won't tell me if anything is hurting, but he just peed his pants (unusual for him) and cried and screamed until he went to sleep. I cleaned him up and gave him some tylenol. I really feel awful or not noticing, so please no judging.
