All by himself

A few weeks ago I heard a din in the bathroom and went to have a look and Johnny had his trousers and undies on the floor, his toilet seat on the toilet, and was climbing up. Twice this past weekend I walked in on him with his step stool up against the toilet, seat up, on step stool, trying to get trousers down to have a wee. He's been out of nappies in the day for about 6 months now, and will be 2 in three weeks time.
