My cheeky 6yo ds became a sulky 7yo and n ow he's 8 he's8 he's rude and at times aggressive (towards his dsis 5). He's outgrown stickers and the naughty stwp but talking doesn't work yet. He's happy to sulk in his room for time out and sorry is just a word. The only thing that works is money. He earns his pocket monet and looses it if he misbehaves. I don't really like using money as a bribe though.
How do you reward and sanction your 8 yo?
