Why am I telling you this?
A few nights ago, I was washing up in the bathroom before heading off to bed, when our 4 year old son came into the hall looking upset. He was half crying because it seemed like he wet himself a tiny bit. It was not the first time this has ever happened, so I instructed him to finish peeing in the potty and then I would get him clean underpants and pajamas.
Instead of stepping up on the stool in front of the toilet, our son climbed up the step stool in front of the bathroom sink. He stood there looking very confused. I wondered if he was about to pull his pants down and pee in the sink? I pointed out his error and he got down and finished his business in the toilet.
While he was doing that, I got him fresh clothes and put them on his bed. Then I went to put the wet clothes in the hamper. When I came back to check on our son, he was making sounds like he was having trouble. Why? . . . Well, he was trying to pull his underpants on over his head!
