Beautiful child.
I agree with Paul; much too blue and Paul's re-work appears more accurate.
I like shallow DOF, but with the arms in the image, find it a bit too shallow.
Kingdon,
Paul is great at this sort of thing, and can probably give you a more sophisticated answer about white balance.
One quick color balance fix is to add a curves layer, select the white eyedropper tool, click on the whites of the eyes. You may need to experiment with clicking in different areas and may need to adjust the opacity of this layer. Using this alone will make the eyes a bit too white. In an image with true whites, blacks or neutrals, use the white, black or gray eyedropper tool in the same fashion. There are no obvious points to use in your portrait above.
