8yr old DS 'weeing ' himself at school driving me mad-quite long message-please help

[headintheclouds]

My 8 yr old son has had a 'dribbling' habit for as long as I can remember and I just dont know what else to do! He doesnt wet the bed ever,and he does not wet himself at the weekend when he's not in school. I pick him up from childminder and he smells of stale urine without fail every evening and underpants are damp-he's not doing a whole wee,just dribbles(but enough to leave a large wet patch)-We've tried ignoring it,addressing it, telling him off, not making a big issue etc. Ive taken him to GP 2 yrs ago who said he'll grow out of it- there's definately no physical cause Im missing(im a nurse and Ive thought of everything)-he just seems to wait until the very last minute until he's literally bursting and then has a bit of an 'accident'.
His teacher has noticed he does want to use the loo alot and thinks he's trying to avoid lessons. We did adopt him at 3yrs and he was a bit late to toilet train because of coping with his move to us etc/settling in and as a result he was nearly 4 before he was dry at night!-Am I just being over-anxious?Part of me thinks he'll grow out of it but I really dont want to be still worrying about this when he's about to move to high school!!He's not in the least bit bothered about this,but its only a matter of time before he'll start getting teased at school I think.
Any offers of advice /similar stories would be gratefully received-is my son the only 8 yr old behaving like this?

It sounds as if he's afraid to ask to go at school. If you contact the school nurse, she will come out and see you and will talk to the school to get it all out in the open with them. It can be difficult for them to go at play time, especially if he's fairly new to all this. Sometimes our bodies can't stick to a timetable and need to just go. If he doesn't feel confident enough to ask when he's in class then it's got to come out someplace. The teacher needs a good talking to IMO. Could she remind him to go at playtime incase he's forgetting and not going?

I had a very similar problem with 6.5yr old ds both at home and school. In the end after a particuly bad soiling incident at school I phoned the school nurse for our area and we went to see her. She talked to ds and gave us some advice about drinking regularly and visiting the toilet at set times. The school nurse also asked us to measure the wee once a day for a week so they could check bladder capacity. Ds is now much improved and his teacher has said he is now asking to use the toilet at school.

Definitely phone the nurse as soon as you can as it seems to be quite a common problem and they have been a great help with my ds.
