Girls, hello, we're one year and 1.5 months old. Our daughter has a temperature of 37.4-37.8, there are no runny noses, she doesn't cough either, but there is just this temperature. I can't figure out if it's on her teeth or if she got sick? It's hard to see the gums all day, she's fussy and sits in my arms all day. What do you think?
