You're obviously a wonderful Mommy! Do all your babies get along? I've thought about getting a playmate for Lucy, but I took her to visit a friend who also has a female yorkie. At first they chased each other around, but then her baby went up on the deck and pouted until I took Lucy home.
I wouldn't want to rock Lucy's world by bringing in another baby if they're not going to like each other.
