Sammy has a bad case of toe jam.
As in...he can't stop jamming his toes into his mouth!
He loves his tasty digits. He gnaws on them until they are a drooly mess. They keep him entertained on the floor for at least a 1/2 hour.
His eye hand coordination is still developing, so the best part about his foot fetish is watching him FINALLY grab hold of a foot and then with the force, speed and intesity of say, me putting a cupcake to my mouth, he shoves that foot in like it's the most tasty delicatessen around.
People say he has his mom's flexibility. At any rate, I think it's pretty cute!
