We got Brooklyn just recently and Oliver is a year and a half. They couldnt be closer....play...play...play. And your theory of Daddys girl....correct! She is a daddys girl. My husband really did not want another one, but, he gave in to me because i wanted a little girl so bad. You should see him with her....it is cute! She smothers him with kisses when he comes in from work! He couldnt love her more. (he thought he could never love another the way he loves Oliver...)My vote.....go for it! Its GREAT!!
