Comfort? No, it's not the nice soft down comforter, nor the memory foam mattress. No, it's still not the bottle of milk, nor the comfy pajamas. It is the 2 balls under each elbow. If you didn't notice the first time, look again. A T-ball under the right elbow and a red foam ball under the left elbow. Troy wouldn't stay still unless he had one on each side. Once he did, it was all peace and rest after that. He is a boy through and through, and we LOVE every minute of it.
