Sharing is caring! I caught both of them sharing yesterday. Twice. They shared a chair and a blanket! Yes, they were watching TV both times, but that is irrelevant.
I brought up a rocking chair from downstairs. After cleaning it up and painting the cushion it was instantly a novelty. A few times I found myself in it as well, but with both kids on my lap rocking! It seems to be harder to hold both at one time! They do love rocking.
