Here's Lily checking out Teagan. She checked that he had eyes, nose, ears, etc were in the right spot. I think she is smelling him here. After she gave her stamp of approval she gave him a quick kiss on his head.
But here is Mike with his nephew. It was so adorable to watch him. Cati is not much of a cuddler with Mike. (She's a momma-girl) So he enjoyed these moments of tenderness.
