Do yourself a favor and make sure to document this remarkable milestone. I usually recommend that we get together in the 7th month so that pregnant belly will be showing but while you can still get around pretty comfortably. For the most part I handle sessions like other portrait sessions where we can include the father in some of the photos and if there are any big brothers or sisters we can include them too. I leave it up to my clients to bring props if you want to use baby shoes or make signs or bring some of whatever you are craving. I once photographed a session with a client who said she was having a lot of cravings for Cheetos so she bought bags and bags of Cheetos so she could lay in Cheetos with her hands in Cheetos bags and I kept thinking that I have that same fantasy but with popcorn and I've never been pregnant. Crazy right! We can do whatever you want... except roller coasters... or trampolines. Years from now when you are hearing the pitter patter of little feet running around your house and you find your child looking at the pictures we took, think of me when you blow your child's mind and tell them to guess who was in your belly in that photo.
