Hmmm, maybe he only needed help with the wiping (?), but I can understand your concern for him.

My DD is fully independent and she is 2years and 3months. Has been for at least a month. By 'fully' I mean can pull down her pants, get on the toilet, wipe, flush and wash hands. In saying this I have many little steps in the bathroom to help her up and down (and I check her hands religously!), so she is more independent at home than she can be when we are out (depending on the bathroom). But sometimes she still asks me to help, just out of laziness and wanting attention I think!

They are definately all different with this stuff!
