I attended a group PPP through a parent & child centre in the ACT. It was fantastic - I found it really helpful at the time, partly because I was able to take hubby & there were lots of other men there so that somehow gave it credibility in his head. If we had stayed there I think I would have gone back for a couple of refreshers. I really like that they emphasize the need to connect & enjoy your child's company, there are all sorts of benefits to the whole family. It was a few years ago now & I'm sure some of it has stuck with us. I know it's one of the parenting systems that has a strong evidence-basis, meaning the principles & tools have been studied & shown to be effective.
