My 10 year old dsd is sometimes shall we say "really pushing the boundaries" when she's with us, but dh has just had a conversation at home with her mum and she's even worse there. We're thinking about doing a contract and rewards/sanctions, but I'd really like to read up a bit more about it and try and understand what's going on for her too. I found Toddler Taming really good and I wondered if Christopher Green has done a book for older children, or if anyone has read anything else that's any good? TIA
