I skipped one year when I was trsf from one city to another one in elementary age. The impact was not showing until I was in a junior high, among with elite students in a "Zhong Dian" junior high. Other students are either one year older than me, or two years old, who got delayed one year. I suddenly slipped down, because I was not mature enough to know that I need to prepare and review study.
My father showed regrets a few years ago, while he was talking to someone else. At that time, I had my 2nd child already.

It is very painful to recall what happened. I need to be very careful with my child.In his case, he won't be too young to compare with other kids in the same grade, but he will be the youngest. Currenly, he is one of the active kids, but not out of whack.He is very outgoing.

Thank you for taking time to reply.Do you see any major difference between boys in your son's circle,because of age difference?
