Pregnancy is one of the great transitions in life; transitioning into parenthood. I am firm believer that it should be documented. It is a brilliant and amazing thing that a woman can grow another person inside of her body!
I have a baby plan that consists of 4 sessions. Some folks like to incorporate the maternity session and the newborn session into that plan: maternity, newborn, 6 months old and then one year old.
We can do it any way you like but I think thats a neat configuration.
