My daughter is 5 years old. She often "plays" rudely with me. For example, she'll kick me, and I cannot explain clearly to her that the behavior is impolite.
Sometimes I kick her (and as a result, she becomes angry or cries), and I have told her that when she kicks me it hurts me (in fact, my daughter understands what I mean, as sometimes she may say "sorry" to me).
Sometimes, I ignore her behavior and do something else by myself.
How should I respond when she behaves like this? How can I best educate my daughter?
