Babies sure do love their feet. I think they enjoy putting them in their mouths just to taunt the rest of us, to remind us of what we can no longer do.
My wife started doing “baby yoga” with our boy early on – primarily a move called “toes to nose” (the description is all there in the title). I would do the move a couple of times then resort to making zurburts on the soles of his feet, to his squealing giggles.
The boy loves the word “feet” for some reason. My wife discovered its calming powers one morning when our son was crying and the usual repertoire wasn’t cutting it. She repeated it a number of times, going higher each time, and he started to laugh.

This is great. I made up so many silly rhymes and songs for my kids. With most of them I’d get stuck and be unable to find a rhyming word. Somehow, that didn’t stop me and I’d try again later until I found something that sort of worked.
I have many that never work which makes them even funnier. (Well, funny to me. The boy doesn’t seem to notice.)
I will nibble them when we get home…………..
I think I’ve said the exact same thing. Of course, my kids still think rhyming is hilarious almost 10 years later. Humor takes a long time to get sophisticated.
Gosh, I hope my kid will continue to think it’s hilarious. I don’t have much material.
