Do you let him take his game boy to school?
My son started to do this last year in Grade 3. I volunteer at his school and watched him at recess and noon hour one day... There they all were. 3 or 4 of them from his class. Sitting like bumps on a log outside, in the sunshine, and never moved all recess or noon hour. I really think this generation of kids will not get arthritis in their fingers and thumbs.lol
My first new tactic was. No game boy at school.. then after awhile we hassled it over and over and the little litigater (sp?) helped me see that I should compromise. I did. (You have to make them feel like their winning some leeway) He now is allowed to take it one day a week. His choice of the day, or sometimes if I know it going to be terrential rains (like it is today, in our area). I never remind him though when he has forgotten to take it...I just let it slide. Sometimes a couple of weeks will pass now and he hasn't taken it to school. But the new, pokemon games are out for Christmas and I'm sure he will want to wheel and deal more to take it to school.. but I won't budge now.
A good question (if you want to know how they are getting along with their friends at school).. that works for me is . So, who did you play with at recess today? And what about noon hour who did you hang around with.. Another one is ..Is there anything that happened at school today that you think I should know...(then wait) or Did something happen at school that you found really funny...
The other compromise I made, in my own mind, is that when he gets home from school he can play "screens" for one hour. I have a timer I use because he tends to want to forget his hour is up and sometimes I get to busy to remember. (It's a little wind up egg timer. Has a little digital screen you just wind it to the time you want and it count down.. the timer ring/buzz it VERY loud.. which is good)
He likes that and it is a kind of unwinding after the day. He also knows that if he makes a big fuss about homework, whining and complaining and such that the "screen" time gets chucked out the window until homework is done.
I don't know if Jackson does this but my guys USED to do this. On the weekend they'd get up at 6 o'clock in the morning and sit downstairs playing screens. I caught on to this, after awhile (I'm a bit slow) . New family rule: No screens, absolutely no screens, T.V.'s, computers, gameboys, game machines until 10 o'clock on Saturday mornings or any holiday or inservice. 2nd new rule: Absolutely "no screens" for anyone in this house (including daddy) on Sundays until 12 noon... and sundays are my favourite day of the week... especially Sunday morning.
What a change in our house. My kids all sleep in on the weekend now... like they need because they are up later on Friday and Saturday nights. (hey, nina and big tex.. it works for us)
Good luck with all the information everyone has given to you both.
