Help! Pregnancy Milestones/Memories..

Reese
I have a Polaroid camera and I'm thinking I'd like to take "milestone" pictures and arrange them in a nice little book for my mom, who lives out of state. It'd begin with a photo of announcing it to my hubby, end with a photo of the baby and include everything in between. 
But what should I do for my hubby and I to keep? Is there anything you did or wish you would have done?
