Question:

Is it permissible to hit children for other than the abandoning of Salaah

Answer:

Some of the scholars mention generally that it is allowed in Islam to hit the children lightly, if it is for the purpose of disciplining, and as long as it is not abusive and harmful. The condition is that the child possess a level of comprehension to understand why he is being discipline. However, other scholars confined it to the children who have reached ten years old and up and others have confined it to the act of abandoning the prayer. And Allah knows best .
