No -- 回复：小孩感冒到底该不该给吃药？

Of course, if your son has a fever, he should stay home.

Explain to your son why you think giving medicine is not necessary.

At same time, I would ask teacher not say "your mommy should give you medicine" to the child. If she has concerns, she should talk to you directly. Giving medicine or not is parents' responsibility; teacher should not contradict your decision.
