Not sure of Mia's age and if you posted and announcement previously..no matter. Congratulations.
Nice photos. I love the concept of number 2 from two aspects: the color and and pose. But have "constructive (?)" comments about both. I like the subdued colors, but wonder of you could fade the flesh tones so there was just a hunt of pink..less so than at present. Now as for the pose (which I generally like) it might be better yet of you could include Mia's hands and crop a tad off the right..and here is the awkward thing. If Mia's head was tilted just a wee bit in another direction, we'd not be looking up her nostrils which are almost dead center.
Regarding 1 and 3 ... I'd pick 1 over three as it is less tight and the hand is a nice touch.
I suspect Mia's life will be well document on 'film.'
