Kimi likes to stand watch over Liam. I think she is his guardian angel... or the dog character, Nanny on Peter Pan.
Ratchet likes to be a part of whatever is going on. He will just come up and give Liam a few kisses then walk away. I think it is his way of saying, "It is ok, Liam. This is all I can contribute."
Kimi makes sure she is right there with me whenever I do anything.
I think they both love the new addition.
