What would you do?

If you had a dc child who was home with a low grade fever, pink eye, and strep. Dc mommy took dc child to the doctors this morning and received antibiotics. By the time dc child received first dosage it was at lunch today. You have a 24 hour return policy ...

So does that mean the dc child can return at lunch tomorrow or would you let the child come in the morning.

Most of my families wouldn't come for the whole day, but this particular Mom is begging me to let her child come tomorrow morning. What to do, what to do....

(I am a stickler for the rules, so breaking them for a family I am not particularly fond of, is really difficult).
