The only boys name I really liked was Daniel. We (well I didn't, my husband did, and sulked when we didn't find out, but I told him he'd regret it when the baby was born, which sure enough he admitted he was glad we waited) didn't want to find out the sex until the birth, so we chose a boy and a girl name. The boys name was definite from when I was 5 months pregnant. The girls name wasn't settled at all.
In that respect, we were lucky we had a boy. (when the midwife said "it's a boy", my husband and I looked at each other and said "Daniel", it felt amazing).
