I think the education of a child should be given to his biological parents, because young people have their own ideas. Sometimes, as an old man, you should know how to enjoy life and don't worry too much about it all your life, because there is a generation gap. If you worry too much about their affairs, it will only make you work hard and not be liked by others. Fortunately, everything is entrusted to them, and they can handle their old age by themselves. This is a place where every old man can make a difference.
As the saying goes, children and grandchildren have their own blessings. Don't use your thoughts to frame other people's behavior. So the problem of the older child becomes an enemy with your mother. Let's just say it's not just your mother. If such an incident is too serious, the most uncomfortable thing is to be the father of my son.
Because both women are the most important things in his life, he is in a dilemma. For the sake of his children's situation, he should give up doting and disciplining his grandson. Give yourself a few months' holiday and travel to relax while you still have strength and energy.
