Alex has been working on holding his own bottle. I have to help him get it to the correct angle to bring it into his mouth, and he drops it frequently, but he's getting pretty good at it. When I'm feeding him solids he's started grabbing my hand or the spoon and pulling it toward his mouth if I hesitate in front of his face. I don't think he's going to have any trouble learning to feed himself.
Here's a cute pic of the boys in their Christmas Eve pajamas. Spencer is on the left and Alex is on the right.
