Baby has a kitty

Matthew has become such a mommy's boy. It seems he can't sleep well unless he is laying on, near, or next to me. I am very much enjoying the cuddle time, but am growing increasingly concerned that he will have major issues when I return to work. I'm thinking maybe I've found a solution.....I've heard of dogs taking on litters of kittens, but I'm not sure how it works for a cat to take on a baby (especially a male cat!). Leo just LOVES to be around the baby.
