Practical advice.. hmm.. I'd better not say anything ...

BUT - because I can't help myself, I will....

My mum faced a similar situation - my friend at school had a terrible home life and was kicked out at 16... so she moved in with me and my sister (we lived together in a unit that mum paid the mortgage on because she was far too busy living with her boyfriend and looking after his kids ) so Tam moved in with us.

She lasted about a month - following mums "rules (which weren't very many) and then moved in with another girl at school who was also having problems at home.

So I would take her in, if it doesn't work out - then at least you can tell your DD that you gave it your very best shot. Anything is worth a try.

good luck.
