What's with the toes?

I'm not quite sure where Emma got this from, but her toes are curled probably 90% of the time. I don't know where this comes from and am not sure if this is a typical baby thing or not but Wes and I don't understand how her toes can be like this and she doesn't get a foot cramp!

It's all the time! While eating, in the bath, playing, in the car, getting a diaper change, laying down, sitting up...you name it! The only time they aren't curled...is when she is asleep.

Take a closer look at these pictures....and check out the toes! This is just a small sample of the pictures that I have with curled toes!
