I forgot the funniest part!!!

So I tried to get him to sit on the potty last night (we're having NO luck with the sitting still :S) and he gets up and starts running around the kitchen. Then he grabbed a measuring cup off the counter & starts running around with it over his bits laugh.

Well that's definitely a portable potty Lucas...

(thankfully it's an old measuring cup I don't use for food any more :D).
