What are these?

We were in the kitchen the other day and I looked down and Will was playing with is feet for the first time. Up until today, he hadn't noticed them before so this was a very exciting moment (who would have ever thought that some day playing with your feet would be a big event!).

Hmm...I wonder what these are?

They look tasty..maybe I can get one into my mouth.

Hey, where are you going. Come back here!

These things are fun to play with mom!
