I have had each of my girls names picked out early and when they were born I didn't even consider changing them. We have had a boys name chosen since we were pregnant with DD1 and we still plan to use it if this baby is a boy.

However, my brother has a newborn daughter and they had a name chosen which he had liked for years (he had 3 boys first) and it wasn't until his daughter was born that he changed his mind and she was named something else (a much nicer name to if you ask me)

I love the name Oliver BTW. We don't have a boys middle name picked out yet but Oliver is on my list.
