What does the father want? I know a few people that have gone through disputes over this and legally they were told because of the conflict they had to have it hyphenated.

Technically speaking hubby and I had only been together 3 months when I fell pregnant (unoffically 18 months earlier kind of on off...) but I wanted my surname as my son already had mine and he wanted his and his son had his surname.... our happy medium was to hyphenate the surnames. Now we're married and will eventually change mine, my sons and both of our daughters over to his surname... will be a bit of a hassle but I wanted them 'linked' to me too.

If your partner doesnt mind then give bubs yours, you can always change it to his later... if he does mind then go for hyphenated... put your name first though because my doctors surgery and most places actually drop the second surname.. even on my medicare card my daughters just have my surname.
