When I go to change Robert's diaper, there's a little teddy bear on the nightstand that he sometimes wants to play with. So when I give it to him, I have the bear kinda nuzzle up against his face and make a kissy sound - like the bear is giving him a kiss.

This evening while I was getting him ready for bed, he started "uh-uh-uh"ing at the bear. So I said, "Do you want the teddy bear?" and handed it to him. He picked it up to his face and gave the bear a noisy kiss on the nose =)
