There are indeed some old people who pursue themselves and work hard when they are young, hoping to live a chic and free life in their later years. They are not wrong!
It is a blessing for the old man to help you with your baby. Don't hold grudges if you don't help, but learn to let go. After all, it is really not easy to take care of the baby now, and the high responsibility demands them, which fetters their later life. People live in the world for only a few decades, especially long after they get married and have children. They are working hard and serving others, and few people stop to take care of their emotions. Parents' actions are also conveying to you an idea that everyone has the right to pursue their own happy life, and people also have the right to live for themselves. So if your old people don't want to bring them to you, you don't have to compare them with other parents.
After all, you are the parents of the child. From the moment you have a child, you must go all out to be responsible for the child. You are the antidote to the problem!
