Cute shots and nice poses. Great eyes.
I don't love the ones of the top of her head towards the camera because you can't see her face, but the light playing off her hair is cool, so I could see why you'd like it. Her hair is a characteristic of her ... something you would remember (assuming your her parent), so something you want to capture.
On a purely technical basis...
Many of these are dark or underexposed. In B&W this is a pretty common "mistake" (I use the term lightly). A buddy of mine once gave me some interesting advice... shoot for one pixel in the image to be underexposed, and one pixel in the image to be black. If you can accomplish that, you have good brightness and contrast in your image. It's not a literal rule to follow, but it's a good conceptal model.
It also looks like you missed the focus on some- particularly the ones of her hair. Just something to be careful of. You can also sharpen any or all of them, though some softness in these may be nice since they are pictures of a child. Up to you, obviously.
BTW, my wife has beat paranoia into me about pictures of children on the 'net. You might consider being careful about pictures of children in bathtubs. I hate to even say it, but as a parent of two girls myself...
Nice shots though
