Okay I have a recent wee story too - although not on the change table as she hasn't weed there for ages.

When I'm drawing the bath, Clara wanders around the bathroom naked. I encourage her to do wee wees, and point at where it comes out.

I was kneeling while testing the bath, and then pointed and looked at her girly bits, about 4 inches from her, saying 'are you going to do wee wees?', and she started to wee.

Okay, not such a funny story as I was just far enough not to get it in the face, but it was close!
