My daughter got bit by what I thought was a mosquito and it's been here for a couple days (she always swells up with mosquito bites) and way today it looks like it spread some so I'm thinking maybe it was a spider now. I'm monitoring it through tomorrow and if it worsens I'm taking her to her doctor. I'm all worried about it but my husband and everyone else is saying she will be ok. Anyway how do you treat a spider bite on a 12 month old? Advice please? No bashing please.
