Scott Woodward is also great. I have used him a couple of times.
His website is
www.scottawoodward.com
Look up the portraiture section to see some of his work as he does alot of other stuff as well.
A Canadian guy and really good at what he does. Also someone to think of once you have had your baby. He does alot of stuff on location such as the Botanic Gardens and has a long lense on his camera so isn't intrusive. Just stays in the background and snaps away to capture candid moments.
He also now has a studio and is working with pregnant women.
Good luck!
