Apparently I am being "uptight" in assuming not that our unborn baby would take only his father's surname, but rather that we would discuss options and probably include both in some way?
Incidentally, partner has been less than supportive about the pregnancy in general, not even sure he wants the baby etc, disappearing every night to "think" without saying where he is going, coming up with little gems of wisdom like "In whose hands was the contraception?" (Now defended by saying it was a friend who said that, not him; but he chose to quote it to me.)
I don't think IABU, am I?!
