popular names?

Thoughts on the name Liam?? I loooove the name and have loved it for years but just found out it's number 3 on top 100, which will probably mean he'll have 5 other Liam's in his Kindergarten class. I know it's short for William but I don't like the name William. I don't even know what I'm having yet, I'm just getting ahead of myself. I know it was annoying always having another Amanda in my classes and now I currently work with two, but it wasn't the end of the world...? So conflicted.
