Can my child go back to school? HFM

Hi!

My girly was out last Friday and through today with the dreaded hand foot and mouth.

Her skin is healed / or scabbed over but her mouth sores are still present!

I want to keep her home one more day.

The mouth sores can’t scab over so I would need to wait until they are healed correct? I see a lot about skin sores scabbed over but nothing about the mouth! Thanks!
