My son and daughter both love their new baby brother, but that's where the similarities end.
My daughter is a natural born nurturer. She wants to hold her little brother while singing to him and rocking him gently. Heck, she even enjoys changing his diapers. It's a joy to watch.
Meanwhile, my son is never sure how to hold him and has no interest in singing to him or changing his diaper. Here he is with his baby brother slung over his shoulder as he watches the hockey game.
