Per your request, here's my feedback. Looks like you have some of the same problem I do, we like to frame too tight! I'm having to work on that myself. This seems to be an issue in several of these here.
On the 1st photo: The baby's skin is too blotchy, and it really stands out in this B&W converesion. While I don't believe babies should look fake or plastic after PP, I think some should be done to the skin to get rid of the redness and blotches that they all have. What program do you use in post?
All the photos seem a little soft to me, either you missed focus, or you are doing what another bad habit of mine and using too shallow DOF.
#2 would have been better if you had backed up more and also got the bottom of the blanket in focus.
#4 doesn't work because you've chopped fingers off of mom's left hand, in my newbie eye it looks a bit overexposed
#6 needs the ankles blackened out too, where only the feet are showing IMO. The ring doesn't look in focus either. There's also something in the upper right hand corner, not sure what that is?
Anyhow, there are tons of tutorials for newborn photography that seem to be pretty helpful. I think it just takes alot of practice. Keep on and you'll get better and better!
I'm new to this too and will be getting the opportunity to be shooting some newborns in November. You can take what I say with a grain of salt by the way! haha..
Keep at it!
