HFMD.

Stay home Don’t let her out unless completely healed Hydrate her Soupy things Smoothies

There only symptomatic meds that can be used to help with HFMD symptoms. Nothing that can cure it other than waiting for your body to deal with the virus. Calamine lotion for the skin itch, cold water to soothe throat, numbing gel for mouth ulcers. Keep hydrated. If difficult to eat, just drink milk better than nothing. If unable to manage at home or if refusing all food and solids, or signs of dehydration, go back to the doctor for their advice.
