Don't spoil it
You can't depend on your children for everything. What he wants depends on whether it is reasonable or not. You can't satisfy everything. Drowning a child is like killing a child.
Learn to share
To guide children to learn to share, let children know that sharing his toys with other children will not reduce the number of toys. On the contrary, everyone can play with each other and become more.
Don't be too helpful.
Don't help children too much. Let the child know that many things can only be done by him alone. Parents can help him, but can't do it for him. For example, when a child reaches a certain age, parents can teach him how to eat with a spoon, but he can't feed it bite by bite.
