As a separated Dad of a newborn, I'm just wondering when to expect the stage where only mummy will do. I've started having him at mine (at around 2-3 months), and he's an absolute joy, but I'm expecting there may well hit a point in his development where this will need to stop for awhile. He is at the moment comfortable with me, is it at all reasonable to hope this might continue? If not that's fine I just want to make sure he is not distressed needlessly.
