We took over DP's nephew's care, permanently, 3 months ago. He had been brought up by his granny since losing his parents as a baby. We took him because he was behaving really badly at school, swearing at teachers, messing around with older kids who were less than kind to him, getting increasingly out of hand at home, and eventually refused school for 3 months of Y7.
He's settled in with us very well. We've got over some major problems at school, which involved him being put in a 'nurture' stream because he was unmanageable.
So we've given him firm boundaries and his behaviour has turned around. He's happy and loves his school, his teachers say he's handing in good work and there are no behaviour problems. But really we're just like a boarding school, he talks to granny for hours on the phone every evening and plans to go back 'home' every holiday. Who can blame him (or her), she's his mum in every way that counts.
One of the problems we are dealing with at the moment (picking battles of course) is his table manners. He eats with his face in his food, fingers on the prongs of the fork, licking his knife and generally appears to have been raised by dingos. Granny has perfect table manners, in fact she went to finishing school.
If this was a typical granny situation I would let her spoil him, but she has already spoiled him and we are sorting out the mess she made. I want her to uphold our nice eating rules (he doesn't even know how to hold his cutlery, he's not being difficult) which are fruit no pudding if no effort. And no alcohol (last year she gave him 3 bucks fizz on Christmas day. He was 11).
