DD is nearly 9 and eldest of my three children. Her behaviour has been extremely challenging ever since she could talk. Mostly severe anger and rudeness, non-compliance, screaming at us and her siblings. She is highly intelligent but I don't feel this should be an excuse for bad behaviour. We have asked for help from many different sources but nothing has worked for very long. Feel quite desperate now as her behaviour is affecting her younger siblings. Can anyone recommend a behaviour consultant / supernanny type / parenting expert who could work with us on a one to one basis? We are based in Hampshire. Thank you.
