My DS is 9, we're having real issues with him claiming DP and I are hurting him when we are really not.
As an example, he was asked to go on time out on the stairs (something we've always done with varying success) so he's on the the stairs making a fuss about being there and DP walked up the stairs past him, I was at the top of the stairs so could clearly see that they did not make contact. DS however started rolling around saying DP had stamped on his foot! 
He is always doing this, I'll walk past him and he'll start screaming that I've hit him or pushed him, none of these things have ever happened. The most we have ever physically engaged with the children other than hugs/kisses and play fighting is when one of us has had to pick him up and carry him upstairs or out of a public place when he's being violent or overly disruptive.
I'm actually getting really concerned that he's going to get one of us into serious trouble for something that isn't going on!
Also I'm worried about why he's doing it, he's fine the rest of the time but as soon as he gets in a strop this starts.
