Baby A on top, you can only see the head. Baby B is laying profile hogging the shot!
Baby A only, to show that there's a whole baby there not just a noggin, like in the other shots!
I love this shot because even though you can only partially see baby A, if you look on baby be you can see the little arm that was just waving around like crazy! ...And I adore that the two sacs almost make a heart. I'm a girl, what can I say!!!
