Riley is a very bright and busy little man for just 16 months old! However, a few months a go when he started pointing at the back of his diaper to go to the toilet and more recently saying "poop" - I was a bit surprised.
I guess he wants to be big really fast - but seriously he is too young to wipe by himself.
Here is a couple of photos of him in action. (FYI - he spilled a drink on the front of him). I also added a cute photo of him and one of him doing his stretches.
