I'm struggling to decide on my baby's surname. I initially assumed it would have my boyfriend's surname, but we haven't been together long and have had many ups and downs. There's no guarantee we'll stay together or marry. I'm beginning to wonder why it can't share my surname. I mentioned this to my mother and she thinks I'm being silly and it should have it's father's surname. To those of you that don't share a surname with your partner, what have you decided to do?
