Just curious. I have a 1 yr old who is constantly rotating his little feet round in circles...even when he's just gone to sleep. It's the cutest thing, and he's been doing it since he was just an infant.
My DD always slept with her arm over her eyes, as in, "What a day I have had today!" It was so cute as an infant, and she still does it sometimes as a 4-year-old! They have the cutest ideosyncrasies!
Well, I don't know if he was always like this but my fiance' tends to move his foot around when he's going to sleep. He will shake it or just move it around like you mention. There are other times he does it also like early in the morning when the alarm went off and he's trying to get awake. It used to drive me nuts but I don't notice it anymore. DS didn't seem to inherit it though.
Leslie, I think that DS got it from me because I do the same twirling thing when I'm trying to go to sleep. DS does it ALL the time...it's so cute. Maybe there's some sort of club like Ankle Twirlers Anonymous LOL
