Feel like I have no control over my 5 year old. He's always been challenging, but I'm finding him harder to handle the older he gets, and he's only 5! He is massively defiant and stubborn. He's very intense and would like attention 100% of the time. He never leaves his little brother alone (age 3), will never play separately and is mean to him about 80% of the time. I feel like I'm fairly strict with him, but he genuinely isn't bothered by consequences. I did a Webster Stratton Incredible Years course nearly 2 years ago to help me manage his behaviour, and I still use a lot of the techniques from that which help, such as 'when/then' and using natural consequences. They work to an extent for getting him to do things such as tidying up, getting dressed, eating etc. But I struggle when it comes to stopping him doing his most annoying things, like the INCESSANT winding his brother up. I run out of things to use to get him to stop...I try counting to 3, and if he doesn't stop I'll take a particular toy off him, but he really doesn't care once it has gone and just carries on. I try rewards to get him to behave...if he does such and such for so long he earns something, but I get fed up of all the games I have to play just for him to behave or do normal things. One of the biggest problems at the moment is he gets up too early and goes straight to his brothers room and wakes him up. DS2 only recently stopped having afternoon naps and is really suffering from the extra loss of sleep, as left alone in the morning would easily have another hour or more. He has been told dozens and dozens of times absolutely not to wake his brother up, but completely ignores it. He sometimes comes in to us first, and is told he either goes back to bed or can quietly play in his room until the sun comes yesterday on his clock at 7am, but ignores that and wakes his brother up. At 5.45am this morning we had the usual discussion, and I said I would take all his Lego away if he went into DS2's room. Sure enough, 2 mins later I find him in there climbing on the bed on top of bleary eyed brother. I took all his Lego as threatened, but he just shrugged and said he didn't care. Without resorting to smacking him (which is bloody tempting sometimes but I don't), what else can I do???
