Coxsackie

Last night my daughter played with a baby who woke up this morning with a fever and turns out has coxsackie ☹️ Even though the other baby was acting ok last night, I know the virus can be spread before the onset of symptoms and I know my daughter touched the baby's spitty hand 😫 I'm really upset and I'm not sure what I can do, if anything at this point, to try to help my daughter fight it off. Does anyone know? What's the best things to do for her if she ends up coming down with it? Thanks 😣

-I will bring her to the Dr if she starts having any symptoms but I'm a ftm looking for advice on ways to help a sick baby, especially a baby with a sore throat- My baby has never been sick before
