When Luke came home from the hospital, Pickles sniffed him once and then she promptly ran away. For the first, oh I don't know, few months she wouldn't go near him. If we were all in his room - she was 5 feet outside of his door looking in. If we were downstairs, she was upstairs. She just really wasn't a fan of the tiny crying little thing that invaded our house.
Now that he can actually see her and "pet" her though, she's warming up to him. Apparently being grabbed and chewed on is fun. :)
