Why are some babies born BIG and some small? My Obs tells me that my baby is going to be a 'good size baby'.. to early to tell how much of a 'good size' she will be but what did I do to contribute to this (not meaning to be negative). Is it genetics? did i eat too much? too many vitamins etc... Just wanted to understand what creates a big baby v average size v small baby.

I do feel like I am running out of room. I am sometimes so uncomfortable. Sometimes when she moves it gets a bit painful... I wasn't surprised that he said she was of good size - hehehe

thanks guys!
