Well done ds for being so independent with the potty...

...but if you could tell me about it before dd2 empties it on the floor that would be marvellous!!!

ha ha. Yes, and then if DD could not constantly be sitting on it (fully clothed) because it's a perfect size chair for her, DS might actually be able to use it!

DS started kicking his post wee or splashing his hands in it or playing with bits of his poo

Astonishingly-despite the emptying, not a drop on dd2.
