Help me, Dr Hellobee.

12 months old.
Three straight days of fussy behavior, hardly eating.
Pulling at her ear - but she's on antibiotics for an ear infection.
Today - won't eat, won't drink any milk (at daycare, she did nurse this morning). Fever of 100.8.
Sleeping fine.
Playing fine.

My husband laughs at me when I say, could it be her molars? Or other teeth? Other thoughts?
