Dear N.,
.....and, you do realize that young children have a short attention span - also I have known a lot of parents who hold their boy child back from entering Kindergarten for one year. I sure do wish that I had done that. One of my son's best friends was a very bright child and well socialized, but his parents held him back and he gained a lot of advantage in school from being more mature. I know, it would be a difficult year between 5 and 6, but if I had it to do over again, I would do it positively !!
My own very bright gr grand daughter is being made to wait one more year to go to K. because her birthday is two weeks past the cut off date, which is very early in the school year. So I had to work to calm down the rest of the family 'because she is so smart'. She will have a better time and chance in school, and be more prepared to pay attention in class. (That is the key to learning, you know, paying attention)
Play games with him that he likes, and he will pay attention for a longer amount of time. Also, your presence while he is doing a puzzle or making a drawing or art project is like GOLD. You and he will become closer and he will work on it longer, remember he is young and will tell you when he is finished. Just act interested in what he is doing and talk to him like you would a dear friend. He will be fine.
I always say that the year before a child goes to Kindergarten, and the year before they can get their driver's license are the two hardest years in life. But not really, there are lots more hard years, but it does kinda give you an idea about how the children feel.
Sincerely, C. N.
