I had the pleasure of doing a birth photography session a little while ago!  Birth photography is big in major cities around the US, but hasn't really caught on in this area.  I'm sure most photographers don't want to be "on call" for their mommas.  I think my recent momma called at 3:15am and I was totally fine with it.  There's nothing like having a baby...so many hopes, fears, thoughts, emotions...  You may get a few snapshots of the before birth and one or two right after your baby is born if you do it yourself, but why not take full advantage of capturing this milestone in your life (and your little one's life)!  I was on location for almost 9 hours and then edited every single photograph individually.  I uploaded over 300 photos to her gallery!  IF I ever have another child (hopefully a few years from now if we decide to have one) I'm going to have someone in the room just to take photographs.  I didn't even have a photo of my husband and I together with our first child the whole time we were at hospital!  I'd much rather be able to focus on my little one and my family than to be thinking about all the different photos I'd like to have taken of us.  Leave all of that in the hands of your photographer and enjoy the birth experience.  If you'd like more information check out my website under Pricing.  I'll try to get some photos of the birth session up this evening!
