When we got Shelby my oldest son complained about the kissing. I told him he would just have to get used to it, it's what she does
Now when he comes for a visit, he walks in and drops to the floor and just lets her go crazy on his face. My younger son does the same thing.
You should have seen her the day they both arrived at the same time! She didn't know what to do, so many faces and so little time.
