Sounds like they are on the track of becoming good buddies...congrats! Tell your hubby don't get too concerned. Let me tell you a much funnier case with my best friend's baby. She bottle-fed her (found abandoned without mommy) from just a few days old so they have extremely strong bond. When the dog was 10 years old she married her hubby and Tiffany got a new step-dad. Oh she hated him because he took her place on the bed and she was no longer the center of mommy's universe. She would jump on the bed in the middle of the night and either pee on her new step-dad's head or sit on his face (we think to try to smother him). To make a long story short, they eventually learned to love each other (actually, I think Tiffy just tolerates daddy but daddy loves her). So you see, if even that relationship can turn around, you have no problem at all
