I cannot abide litter. It drives me nuts and it's a real bugbear of mine so my children have always been taught that they put litter in a bin or the stick it in their pocket until they find a bin or bring it home etc.
DS is 8 and I have caught him 3 times in the last week chucking a piece of rubbish on the ground outside. A couple of sweetie papers, match attack wrapper etc and I am really cross with him. Obviously I made him pick them up and put them in the bin but he didn't seem to care very much.
There is a litter pick in our village every couple of months where volunteers go round and tidy the place up. Would IBU to make him do this next week? I'll obviously go with him but I think it would be a great idea as it may make him see how much mess these little bits of rubbish make. DH thinks it won't make any difference.
