Very helpful. It can help children adapt to the environment more easily in kindergarten, integrate into the group more easily and be more willing to communicate. Different from when we were two or three years old, people are far apart now. In the past, we had many parents, brothers and sisters, many contacts between relatives, many children of the same age who could play, and many exchanges between neighbors. This is not the case now. At present, most children have little chance to contact people outside their relatives in the new environment. So don't think that I will get used to it easily, and so will my children. Actually, it's very different. So I think this aspect should be artificially strengthened through intervention before entering kindergarten. And the early education center is a good choice. My daughter spent about half a year in a nursery-style early education center before kindergarten. Compared with kindergartens, teachers in early education centers are less like teachers, more like playmates, taking care of children, playing with children, etc., and doing better than kindergarten nurses. Kindergarten teachers feel more like teachers and have a sense of distance. Therefore, in terms of intimacy, the early education center occupies it, and it is more difficult to integrate. It is very helpful for children to try a collective environment that is easier to integrate into before they enter kindergarten.
