Thank you to everyone who has shared their own painful experiences as well as the very practical techniques they've used to educate their children.
I'm expecting my first child at the moment and this issue has been at the back of my mind for a while now. I've not known where to start with educating our son when he's born nor about situations I need to be particularly careful about. I was raised by what I consider to be very protective parents and looking back, I understand why they were the way they were with regards to baby sitting and sleep overs.
Thanks again, everyone.
