Just sharing this as inspiration. I thought this was an outstanding baby session including the photographs of the big sister and mom with the baby as well. This is not my work. If you click on the image you should be taken to the photo album where there about 5 more rows of pictures to enjoy.
I ran across this photographers personal profile and photo albums while looking around on Photographers Unleashed a place to share and grow and make mistakes together. http://www.facebook.com/groups/photogsunleashed/
Unfortunately I could not find her Facebook business page or web site. If she sees this, perhaps she will email it to me so I can add it to this post.
