There's something really special about those months you spend growing that little baby bump.  There's a exciting anticipation, what will baby look like, whose eyes will he have, what will his cries sound like, what will those precious snuggles feel like.  As you welcome that little bundle of joy, they grow fast and time rushes by, it's easy to forget those early moments of wonder.  That's why I think a maternity session is so special.
