Bubbles and kids should be fun, maybe make for some action shots (defintely will make for some action anyway!).
In this set, the one with a sparkly thing to her left is hard to make out what it is and it's kind of sticking into the side of the photo, might have been better moved in closer or out of the frame. I think something like a brick background can make the angle/perspective more noticeable.
The face is priceless in the second one! Just needed to be framed lower so her fingers were completely in the photo, and would've helped to have someone check/arrange the hair after putting on the hat. Of course none of that may last for long, young ones are just too much on the move.
You could try doing test shots with a teddy bear stand-in or something! and figure out something to use as a physical 'cue' as to where to stand. We often used carpet squares at school (probably donated by local paint & carpet stores), or soft plasticky circles that were in the gym equipment; depending on the stage & age it helps young children to show them where to stand/sit (and they'll only stay so long!).
I think the posed photos will work better when she's older, she's probably just still at that active stage. You did get some fun expressions!
