My 7 month old daughter has only taken her second dose of omnicef. This is her 4th antibiotic in a row for an ear infection that started 3 months ago. So far she hasn't had any problems with this antibiotic (and luckily any other antibiotic), but I will definately be paying closer attention to her behavior at night after reading this. She really hasn't slept very well since she has been sick anyway. She has had red looking stools, but her MD told me she would so I wasn't concerned.
