My little Krystal is 5 months old today. I had my gall bladder out 3 days after I got her, was home with her for two weeks and we really bonded. But she loves my husband, all four boys, and the cat. (he's last, he doesn't play with her) One of my boys will get down on the floor to play with her, so he's the favorite son. Have your girlfriend get down on the floor on his level and play, give a treat, maybe even brush the hair. Keep doing this and she'll quickly become a favorite.
