You need to look at both the histogram and the highlights screens. It can be hard to get an even distribution, so you also need to see if any highlights are being lost. If so, are they important or can you allow them to be lost.
I think you did quite well. One minor criticism might be the distracting toy right above the baby's face. As for the histogram, it *should* be skewed to the highlight side since the scene has lots of white in it. What you wouldn't want to see is the curve pushed up against the edge such that it looks clipped--that would indicate overexposed highlights. I'm betting yours doesn't since the whites look just right to my eye.

Actually, it's the opposite. Lots of white in a scene tends to cause the camera to underexpose. The general recommendation, for example, when shooting bright snow scenes is to give +1 or even a little more to compensate for the camera's desire to render a scene as average brightness.
