Children's affairs can't be changed in a day or two. You should be mentally prepared first and grow up with your children.
It is recommended to know the child first, and don't expect too much from him in everything. It is normal for the child to be naughty. However, the issue of principle cannot be compromised. This should also be based on reasoning, and reasoning should also pay attention to strategy. Think about problems and methods from the perspective of children.
Try it, learn to be a competent mother slowly, and then the child will grow up better and healthier.
