When I worked in infant photography I found that parents order prints in all sorts of sizes, and in order to make sure that you can easily fit any of the shots to look good in any print crop you have to shoot loose. Shooting tight could mean that you can't fit a shot into a particular size print, which is bad. Personally I think the loose composition lends to some really great story telling, adds a peaceful and unique mood, and also keeps the client from missing out on certain prints of the shot because it wont properly fit into the crop.C&C per req:
1-4: In general too little child and too much empty space. I would tighten up the framing and look for elements which don't cause the child to be lost in the frame (esp. #4!) and don't compete with the eye for attention.
5. Step back a little, open the composition up a bit; this is just a bit too tight, 'though without the Dutch tilt, it may have worked better. I would also revisit the conversion and see if you can recover any of those highlights in the clothing.
6. What??? That should have been deleted in-camera!
