We have three boys and a girl. Didn't know the sex of any babes until they arrived. Had the boys names pretty much picked out ahead of time for the first two, and for the third, just had to narrow it down at birth. We had too many for him James Anthony Micheal Edward S(surname). Took out the Anthony and Edward and ended up with James Micheal S(surname). Interesting though that with the original listed names, the initials would still be JAMES. So it was meant to be. With dd, had NO names picked out ahead of time. While in the hosp., I had a theme song for a kid's t.v. show going through my head... and the name Emily. Then... the story of Winnie the Pooh and Christopher Robin... so the name Robin. Emily Robin S(surname). Expecting baby #5 in July and will not ponder names until baby is born. We trust the names will come to us when the time is right.
So... don't stress about names so much! Just enjoy the pregnancy journey because it will be over before you know it!
