How old is she? My SIL went through a hard time at 15. Smoking, stealing. She's way over them both now. I think the smoking is only avoided at the moment coz she's sick of DH & I trying to push her into having one when we are with her, lol.
The stealing...well, not a nice story. MIL did alot to try & stop it, one night she took $50 out of BIL's wallet, lied & called MIL a b*tch...well MiL saw red..back handed her knocking her over the coffee table. Very rude awakening...She hasn't done it since though.
My sister got picked up by the police at 16 or 17 for shoplifting an eye liner. Rang me & asked me to pretend to be mum when they couldn't get hold of her. Told her, no, sorry. This is something you need to take the consequences for.
Maybe now you know all the adresses of the other kids, next time you get a message from the school you could call the truency officer yourself & give them the addresses & let them deal with them?? I don't know much about that or who you contact though.
As for smoking. I know people who've sat their kids down & made them chain smoke til they were sick. Not nice, but worked for the ones I know. Just did the 'well your a grown up now' thing & treated them like a grown up.
don't know that I'd try the smoking thing personally, but these are things I know have been done.
