I like to think of maternity sessions as updated engagement photos...except this time the love between you has deepened, there's a pretty solid addition to your torso, and there's excitement and anticipation of a new partner in crime to share your life with.
At one point during the session when I was trying to get some portraits of Ben, he mentioned how the session was mostly about Shayna. And while in a lot of ways I agree--because pregnancy is beautiful and a huge transformation for each woman in her own way--there is still another involved. In this case it's Ben, her loving husband. The physical aspect won't affect him the same way, but he will experience the life-changing milestone of becoming a parent to a precious being he helped create, and that deserves to be documented as well.
