Check the Cherubs organization, alot of photographers sign up to do 'Cherubs', and are all over the country. Some do studio, some do home visits.
This year I started doing newborns and maternity, but I'm down south in Bournemouth. Also, I only do 'home studio' at the client's home with natural light, so if you are thinign Sears/JC Penny's, check the Cherubs people and see who is in your area.
http://www.cherubs.uk.com/index.phpActually, for newborns, I try to get them as fresh as possible, at 7 weeks, you aren't going to have a sitting up smiling baby, so you need to be aware of what type of images you can get with a 7 week old, so you aren't disappointed. I do newborn, then do 3 months, 6 months, and 1 year. At each of those ages, the baby reaches a different milestone, and that's what you want to capture. Hope that makes sense.
