my daughter has a fever of 101.1.. i think it may be because one of her top teeth is trying to come through although it's hard to tell cause i can't get a good enough look. she's been around a lot of other kids lately so there's no telling if it's something else. should i just give her some tylenol (which i did) and check it again in a couple hours? she's never had a fever before so i'm not really sure at what point it becomes more of a worry. she's 7 months old.
