My FIL and my dh have this weird nervous twitch in their chin, my dh always thought it came from nerve damage when he had a nasty accident when younger but it can't be.
Both of our dc have this chin thing too, it looks like they are cold iykwim, even the GP was a little by it when he saw ds, it is quite odd, dds doesn't do it as much now and has gradually slowed down the older she gets. When you put your finger on you can actually feel it moving, its so odd.
Anyone ever seen/ or heard of this before?
Have said to dh well at least you won't ever need a paterntiy test! they are DEFINATELY yours! lol
