I took a few "last bump" photos when I was in early labor, but none at the hospital until after he came out (and then my MIL took some photos, including D holding him for the first time, him handing E to me, and the first latch, for which I'm eternally grateful). I'm kinda annoyed with myself in retrospect--I had brought my nice camera and promptly forgot about it!
If I have another LO I'd love to have some birth photos taken!
