Rash on cheeks


Can anyone tell me what they think this may be on her cheeks? It started forming yesterday afternoon and by the evening looked like it was going down. This morning when she woke up it seems to have gotten worse. Any ideas?

Some information, she’s on day 9 of Amoxicillin for an ear infection, not sure if that would cause a reaction at this point and she hasn’t tried any new foods, she had peanut butter that morning but it was about her third time trying it this week, so not sure if it would be a late onset reaction.

Thanks guys!
