I like 2, 3, 4 as a sequence. I'm not sure 2 is in focus, however.

As a note for future work, as a parent I would want at least one shot to show her face. As the others noted, crouching down and moving your location would accomplish that. An objectionable background can be blurred out with depth of field, or minimized by getting closer or moving your location. You need at least one adorable face shot.

If you're not her parent, or not presenting these to her parents, then I think 4 is the one that works as a stand-alone shot.
