Hello, I wanted to ask my daughter (it started today) about red cheeks and a red nose. She's been a bit capricious. For two nights in a row she slept terribly. She woke up every hour and cried a lot. There's no fever. And it's not really tearing, but three times it has. I thought it was because she overate. Could this be related to teeth? Although her gums aren't red.
