I think this piece has a lot of potential and I like what others have suggested.
As from me, I have the same problem when I illustrate things; it's natural for me to instantly draw characters doing nothing (like staring into empty space, behaving like statues, etc). I think your character may have the same problem, so always draw your characters doing something, even drinking water or walking somewhere. This will add a sense of liveliness to any illustration. Illustrating is essentially storytelling, anyways as you wouldn't want to read about characters doing nothing. If she was fiddling around with the toys in her crib, reaching for something that's out of picture, etc, this would help, I think.
Hmmm, I wonder if this is why it's important for us to grab our sketchbooks and pen, go out in the community, and draw people. I think this would allow us to shake off this bad habit.
Anyways, good luck!
