My 6 year old boy has a problem with controlling his anger and will periodically lash out/kick/hit me when he gets frustrated. He always gets immediately punished by being given a time out/sent to his room then a stern talking to. Besides this, he often causes a massive scene when getting ready for school, it doesn't help that his sister always does what she's asked (she's 2 years older). The problem is with rewards. I now have the problem where the treat I've bought them and was planning on giving them this weekend, I now feel I can't as he's not deserved it but why should his sister miss out (it's a wii for both of them to play on together at weekends). I'm starting to think a wii wasn't the best idea to improve behaviour but I've got some idealistic view that with the right rules, we can make it work and it'll be better for them than being hunched over the iPad (we have rules governing when they can use them and for how long etc which he abides by). Any advice?
