>My brother remarked worried at that he didn't feel any connection/attachment to his newborn daughter at first - it grew over time.
Normal. A connection with your child doesn't just happen when they're born, it develops over time. I was afraid that I would be unable to develop a connection and bond with my son, but after a few months of being around him and caring for him, we bonded. I think it's one of those things that gets easier, like if we had a second child before splitting up I probably would have bonded even faster, the first one brings with it a host of feelings that I had never felt before and had difficulty dealing with in the beginning.
