I am fortunate enough to have a large house and garden. As a result, my home has become a magnet for the neighbourhood children and my DCs' friends spend a lot of time here. My DCs do get invited back, but I do more than my share IYSWIM. That's fine I always wanted the kind of home where DCs friends felt welcome.
Anyway, I have a policy here of not feeding anything except fruit between meals, as DS2 won't eat dinner if he's had much at all. I also don't routinely feed these kids, as I do occasionally feel that the other parents are taking advantage.
Yesterday morning one of his DS1's friends (calling for DS1 on way to school) told me his Dad has put him on a diet because he's getting "chubby" and he doesn't want him to get fat like him (dad).
Now, the boy is anything but chubby, he's skinny in the way that 11yo boys can be, without looking particularly underweight. Mum is painfully thin, 5'6" and probably less than size 8. Dad is a big tall man, but not fat IMO. The boy often asks for food at my house which I generally refuse in line with my rules for my DC.
Should I be feeding him? I did tell him his Dad's talking nonsense which was probably the wrong thing to do, but I wasn't having my DC think it's OK for a skinny 11yo to diet. What else can/should I do?
