Bigger than normal?

[soy.lor.n]

So I took my monthly weigh ins tonight and noticed something, it is probaly normal but I wanted some input from people with full grown bp's. I have a 07 normal bp (hatched around July 07) she is currently weighing 650 and has a huge head. My biggest bp is a 06 pastel that weighs 800 and my normals head is bigger than hers. Anyway my questions are is my normal going to be just be a big girl? Is my Pastel growing slower? Am I loosing my mind? I can get some comparison pics up tomorrow if need be.

My 7/07 girl is almost 400g
