James has always used his feet as a second pair of hands. Exhibit A:
When he was exploring his hands with his mouth, that meant all four of them. If we gave him something to play with so we could get his diaper changed on the changing table (because otherwise it was like trying to pin a diaper on a thrashing ferret), all four hands would be used to explore and handle the play thing.
What is it with the feet?
I get the going barefoot thing because I do it too. I just can't see using my feet to help me read. Or fling (not kick) items across the room. Or being used to help tell me about a new object.
Maybe I should try it. Even Mommies can learn something new every day.
