these all look soft to me. what was the setup for these? the light seems a little harsh in some, especially #3 and #7.
did you shoot these wide open, like at f/1.8 or so? I noticed in these a very shallow DOF. for instance, in #5, I can tell the baby's face was the focus point, but his right shoulder starts to go OOF, and his left shoulder is very OOF. Same issue with #4, and in #1 where the baby's face is the focus point, but his ear is OOF due to shallow DOF.
I would close up the aperture a few stops for most of these. the picture of the baby's foot is the only one I MIGHT go with that shallow a DOF, but even on that one maybe stop the lens down a little to get the picture a little sharper.
I like the poses, and i even like the balloon behind the baby's head.
are you using off camera flash or a window as a light source? if off camera flash, it needs to be diffused more, and possibly brought a little closer to the subject.
it looks like you had a fair amount of light in the room, so there no reason not to stop the lens down. you will get more of the baby in focus, and a sharper image, as most lenses are not their sharpest wide open.
what you have here is the ability to reshoot as much as you want so take advantage of that!
