DD2 was exactly the same. We just slowly started having DH do things that I would normally do. First off I would be in the room, then after a few days I would just go in the beginning and now she is fine. All nappy changes while he was home, bathing the girls, holding her in the kitchen while I cooked dinner, burping her straight after a feed (still BF) Sitting next to her at meal times (doing BLS). Now DD2 loves been with her daddy. She still prefers me if she is really upset though, but so does DD1 and she is a daddy's girl.
