I recommend Siang http://lightphoria.com he is AMAZING. (Click on Gallery for the baby pics).
He photographed my wedding as well as my sister's, and he also does baby pics. You can't find a more skilled photographer. He's a really nice guy and does a great job finding amazing photo ops on the spot, knows how to create the perfect pose, and he's really comfortable to work with (he made our engagement photo shoot feel like a romantic date).
LOVE her work!
I would also suggest K. Fenton Photography. She's done several sessions for us including a maternity session and we loved them all!
