Thanks guys for your responses! We're going to go with the names.

I also found this great site today where people who have the name rate different aspects of it, whether they like being called it etc: Skye | Should You Name Your Baby Girl Skye | Baby Names World

Campari: We did think of the Isle of Skye thing - we have no connection to Scotland! I figure I'll try to get around it by using "Skye and Isla" when I use the names together. Skye is the presenting twin so should be born first so that makes sense!

LimeSlice: My hubby was wanting to wait and see what they looked like before deciding but I think we're pretty certain that "twin A" will get Skye. I've had so many ultrasounds over the pregnancy that I already feel like I know their different personalities!

Thanks again!! Argon
