We could really do with a good book that gives my dh some sound advice about the best way to approach the relationship with our 13 year old dd. As she gets into her teenage years the relationship is getting more difficult and I feel he is making too many mistakes that is erroding future trust and understanding between them. He didn't have a great experience of parenting himself and is a bit lost on how to act in situations of conflict. Can anyone recommend a useful (not patronising) book that may make him think about healing his own wounds from childhood at the same time as improving his relationship with dd?
