Kindergarten woes

My little itty bitty baby is going to Kindergarten in less than a week and yes I am a nervous wreck. Is it bad to not want your baby to grow up? I really wish I could hide her from this crazy crazy world so she doesn't ever see any of the evil out there but I know that to be a good mom is to let go sometimes. I'll be crying all week...please keep me in your thoughts :(
