DS1, who is 6 in September, has always been energetic and but recently his behaviour has really gone downhill. He is frequently very rude towards DH and me, can be quite aggressive, towards me but particularly towards his 2 year old brother and seems incapable of listening at times. I will often say something like 'please don't eat with your mouth open' only to see him doing it 5 seconds later. (Not sure if I'm expecting too much here, but have a real thing about eating with mouths open, and this example could equally well be applied to other things!)
He also talks pretty much constantly. It's sometimes like a stream of consciousness, which can get very wearing at times. If I don't respond, I often get no-one ever listens to me type comments. I frequently get 'I'm bored' and like someone on another thread, he seems to need constant stimulation involving a third party to avoid being 'bored'. He is a v sensitive boy, and can get upset v easily, lots of crying for not much and a mild telling off can result in major tears.
Interestingly he is well behaved at school, and most of the time at his friend's houses, and the teachers all rave about him. He sits still (v rare at home!), concentrates, is kind, helpful. Not meaning to boast here, but just trying to give full pic. Obviously I would prefer it this way round, the bad behaviour reserved for home, but his rudeness in particular is really getting me down and we're not sure how best to deal with it.
It sometimes seems to me like DS can't actually cintros his behaviour, or maybe I'm being far too lenient and there needs to be more of a consequence to some of his actions.
Any advice gratefully received!
