I was looking at recent photos of DS1 & there are so many where the hand is on the crotch.

Someone posted a few months ago about checking for sneaky wees & I've run with the idea. If he says he doesn't need to go & I know he does I say 'well lets go to the loo & check for sneaky wees' & put him on the loo and lo & behold there was a sneaky wee!
