My DH and I had decided on a girls name and had a couple of potential boys names chosen when we lost our angel at just over 8 weeks. They are still the names we have chosen for the baby we have on the way, but I think because we never knew the sex of the first baby and never actually started calling it by a "real" name, that we have never felt uncomfortable using those names for this baby. If our angel's pregnancy had been longer and we had known the sex, it might be a different story because the name may have felt more like it "belonged" to our first baby...
