We married after we had already had 3 of our boys and I kept my surname. I always thought I would get rid of it as soon as I could as its not common and I have to spell and pronounce it all the time.
We gave the boys both our surnames but not hyphenated. This way I figured they drop off my name (its first) to be used as another middle name and just use their Dads if they wanted too. Number 4 has both names, as will this one when she decides to grace us with her presence.

I think naming your baby is such a personal decision and you should do whatever works for you and your happy with. We got so many negative comments about our boys names that this time we have kept the name to ourselves and nobody will know till she is here. It is driving eveyone insane but why should we tell them only to have the negative feedback?? No thanks.
