my 3 year old takes what you say literally. Parker still had a pull up on and I said take it off and put on some underwear. He was in the bathroom for quite a while and I knocked and went in and found 20+ pair of underwear on the floor and about 5 already on Parker. I said, just one pair is enough. So out he comes with every single pair of clean underwear he owns on! So we made a counting game out of it.
