Hi Christine, A reward system helped my little girl meg whos 7 diagnosed in October, she was able to do them after a week ( and she had quite a bit of money in her poscket !)however I don't tend to press her to much now as we are trying to avoid her tummy coz its a bit lumpy and its a nit tricky for her to do it in other sights as we are still using syringes. Have you perhaps thought of Diabetes uk children weekends these are parent free and he would get loads of support from the doctors and nurses and would see other kids doing this. Alternatively have you thought of joining a local group so he can make friends with other diabetics. I guess this is a problem that needs tackling soonish otherwise it will be difficult for him to stay over at friends houses ect, if it helps he can PM Meg through me for a chat. If it was me ( and I know our kids are all different) Id be thinking of an incentive trip away/new kit/new PS game and then chip away at the problem. rewards work really well with my child, I appreciate hes a little older but I suppose no kids too old for a special treat.
good luck and keep in touch x
