I have a friend with a kid whose a bit of a monster myself. Don't get me wrong, he's not always a monster - Only around his mother.
His behaviour with his mother there is to kick her, bite her, swear at her, throw things at her any anyone else present at the time, make racist comments (He frequently calls his mum a forking black ***** - even though she's whiter than an anaemic snowball) and to break things. He's also threatened to shoot classmates.
He's 4 .
Now, when he's not with his mum, he's sweet, well bahaved, and does what he's told. I spoke to his mum about it, and her reasoning, which I supect leads to her suns abusive behaviour towards him and in her presence is ' My last kid had a cot death, and this ones autistic. I don't want to be hard on him in case he dies too'
With me, I'm a pretty strict parent to my own kid - its the way my parents were with me, and while I dont agree with everything my parents did, it worked . My daughter knows, at age 4, what she can and can't do around me, or around others.She knows she CAN do it if she wants to, but that there will be consequences she won't like if she does. My friends kid knows the same- in my house, its my rules - you don't swear, hit, or throw things.
Kids WILL be kids - and even the best kids will have periods of misbehaviour - but even the worst kids, with persistant and firm discipline and guidelines will improve. I just wish my friend would set those guidelines in her own home. Theres really no such thing as a 'bad' kid - sure, there are some kids who are little monsters as a result of either a mental disability or lack of disciplnie and boundaries, but none that are wholly 'bad'.
I think Friend giving it another go is a good idea - but would still suggest mentioning something to friend D . It doesn't have to be harsh, just simply mention that there was a small problem, that theres a little concern, and that you hope it can be dealt with.
The suggestion of having a set person in charge of all the kids is good in theory, but from personal experience I know that supervising and caring for one child is a challenge at times - and supervising 10 alone is near impossible.
I hope the situations resolves itself anyway ^ ^
