Even if your daughter is wrong, don't hit so hard. After all, he is still a child. Maybe you were angry. Otherwise, how could you be willing to lay such a heavy hand on a daughter who is only two and a half years old? In fact, people's psychology is wonderful, sometimes good and sometimes bad, but it takes patience to educate a child. Be careful. Wait. I hope you won't do it so hard in the future. I am a mysterious child. I hope you don't let your daughter leave a bad shadow, which will haunt him for life. I hope you are careful in educating your children. If you don't educate yourself well, you can let your wife educate him together, so that you won't make too many mistakes. Your wife is still measured. I hope the answer will help you.
