My 6 year old son is completely different behavior wise with his mum than with me, ie, very bad for his mum and anyone connected , grand parents etc but he is a model child for me...I've been divorced from his mum for 5 years and see him 2-3 days a week... at his mums he will kick , hit, swear, have massive tantrums over the most minor thing, try to break things in the house , the list goes on. He's quite well behaved at school and when he's with me he's like a different boy altogether, always helpful, listens, if he's told he can't have or do something he accepts it without a hint of a tantrum, of course he has times when he doesn't always do as he's told but is never disrespectful and it's never anything major. His mum, my ex is getting upset by his worsening behaviour and innit not sure what I can give as advice to help. I'm not a fan of branding kids with disorders like adhd as this seems to be happening far too much these days rather than the parents taking responsibility so I thought I'd try and get some actual advice here....thanks
