I loved #1 and #3. All the background colors worked great with her outfit and your control of DOF was great. Most of all she is sure a cute baby.

I like 3 the best too. When I take pictures of children I'm always after trying to catch them unaware than I am there, engaged playing with a toy or something. 3 is really special because you've captured that, you can't help but wonder what she's thinking as she's touching that tulip.
