The socks are comin' off

As I've mentioned, one of El's latest fascinations is with her own feet.  If she's on her back, they come up near her face.  If she's sitting in our laps, she tries to flop forward and bring her face down to them.  I've gone into the nursery to get her up from a nap, and the toes of her socks have been wet.  But today she decided to take it up a notch:

There's only one problem with her getting those socks off - her feet are cold enough with them on (which is clearly something she inherited from Mom).  Of course, she doesn't seem to mind her yeti feet, so I guess it's not a big deal.
