My 8 YO son is a lovely child - kind, polite and bright. But lately it has become very difficult to make him make an effort of any kind if he's not in the mood to do so. E.g. when he has to do his piano practice/homework/tidying up, he will declare that he's hungry/thirsty/wants to go to the toilet/tired etc. or try to have a conversation on another topic etc. He will also do things slowly without putting too much effort in it (e.g. sloppy handwriting) and moan or cry as soon as he hears criticism. I try to encourage and reward him and not to critisize him too often, but I feel that I have to try out some new strategies. I must say that he's the eldest of 3 children (the 2d is 5 YO the 3rd is 4 months old), so maybe he feels that I'm more demanding towards him than towrds his younger siblings? Anyway, I'd be grateful for any advice, as I feel at my wits end at the moment.
