You could be 100% right about the emotional involvement regarding the dumping methods...
but...regarding the photos I think what we see in the photos as outsiders is totally subjective. Personally I see a young woman who is good in posing - and I don't mean necessarily anything fake - but knows how to pose for the camera, how she looks good, how to smile, how to set up cute photos etc. I see a really cute photoalbum with the child with a lot of costumes etc. What about some natural photos? Where there was no celebration or dress up occassion? Haven't seen many of those? She could have easily taken some nice photos with the kid where mom also looks cool and funny and then just hand the baby to her mom.
Just saying...Did you see any pics where the child kisses mommy, has her arms around mommy's neck, chest, holds mommy's face, etc? Casey looks like a cool younger aunt who when visits she takes this fun cute pictures with the child to post on her myspace account. It is dress up fun time. My own subjective opinion of course that could be 100% wrong.
