so i've been told this year's strain is the worst in a decade. my daughter hasn't ate much, nor drink much today. she's been coughing but mainly resting all day. she has the fever, and woke up with very dry chapped lips. i took her temperture earlier and it was at 100.1. she keeps complaining that her head hurts and would cry. so i wanna know, when do you take your child in to the er??
