Here is to remind myself

Your children are not your children. You cannot do everything for them, neither can you make sure they will have a smooth life as you expected even though you try the hardest. Sometimes. It is not a bad idea to stand back and watch them suffer from their own problems, as the problems are important lessons for them.

When they are treated unfairly, be an example to solve the problems elegantly. Conflicts are everywhere. They cannot be avoided. What we need is to learn to solve them in a smart way.

Your time with them is limited. If the time you spend with them cannot make them grow more confident, love themselves more, then it is not spent well.
