First, the right to have a border with the baby is easy to disagree. After all, they are two generations, and their cognition and habits are completely different. Therefore, the most important point in Separate child care is that "rights should have boundaries". Old people take care of their children and need to delegate power to parents who educate their children! Don't secretly break the rules set by parents for their children. Otherwise, in the "struggle for power and profit" with the baby, it must be the child who is finally injured.
Second, participation should have boundaries. The so-called participation must have boundaries, that is, many times, parents of children can't take care of their children because of work and other reasons. But after work, parents must properly participate in their children's education. Don't let old people "do everything for their children". They always feel that their parents are inexperienced and incompetent, and they dare not let their parents participate in the whole parenting process. If the elderly participate too much, it will easily lead to parents' "no parental consciousness" and "no sense of responsibility".
Finally, I want to say that Separate child care has to make a choice in many cases. However, not all elderly people are suitable to participate in children's education. Many old people, in the process of taking care of their children, will have many adverse effects on their children's growth because of wrong or outdated parenting experience. If the elderly really can't do "participation has boundaries" and "rights have boundaries" in their children's education, and the parenting conflict between the elderly and their parents is far greater than the benefits of helping to look after the children, then please find ways to take care of the children independently!
