He rhymes now too
As soon as I'd made it through five, which is Wyatt's favorite part of the song because I say "behive" instead of just "hive," which sounds funny and changes the cadence of the song . . . he piped up again and said, "one. bum." (We name body parts after the bath, and bum is one of his favorites.) I then proceeded to sing the song again with ". . . he played one, he played nick-nack on my bum," and upon doing so, Wyatt immediately blurted out, "chum." Now he was just screwing with me!
I had not really thought about when a kid learns to rhyme. But apparently it happens around two, and it is quite charming.
