Not early. The lack of sex education is largely due to the lack of clear enlightenment education on gender awareness of men and women when they are young.

First of all, with the rapid development of society, children's physiology and psychology are becoming more and more precocious, and it is inevitable that they will be affected by too much fragmented information every day. Children have no obvious discrimination ability, so it is inevitable to follow imitation.

Secondly, kindergarten is in the transitional period from primary school to primary school, which is the best period to cultivate children's self-care ability and living habits in daily life. Some simple enlightenment consciousness of sex education is necessary. Tell them what they can and cannot do. Children accept it easily.

Finally, children's general safety awareness is not high, and parents and teachers can't always accompany them. Starting some enlightening sex education activities is indeed more conducive to the healthy growth of children's body and mind.
