Love for your kids

I have a 10 month old, Scarlett, and she is the apple of my eye! She makes me absolutely giddy! Everyday I look at her and I'm just so excited she's my baby. So I guess my problem is (I'm pregnant with my second) how could I possibly love another baby the way I love her. Everybody tells me that will all change once baby number 2 is born. And I believe that, it's just so crazy to think about. My love for Scarlett is so beautiful and unique it's a little scary to think I'm going to love another the way I love her. Anyone else have these feelings before their second showed up?
