I forgot to add this to my post. My friend Anne Marie said I needed to get a Wee Block for my friend to use with her little boy. I thought it was disgustingly cute even if it didn't end up being practical. After all, it's my job as auntie without kids to bring silly things like this.
Anyway, it's called a Wee Block and it's good times. I got the Whizzz Kid one. In addition to covering his bidness, it's all spongy and absorbent.
Considering he had just showed his prowess at peeing and pooping all over his mom, I think this wasn't too soon. I can crow since it was technically my present, but not my idea. Thanks, Anne Marie!
