Very beautiful and sharp features; however the holding fingers in the first image is really troublesome; i have a request too; kindly avoid the dog's image here ; you mentioned "one of our recent customer" only in the beginning, and showing dog in the series is not a happy thing; if the baby's mother sees, she definitely feel hurt, i am afraid (the dog's image has come out equally well though)
I'm guessing you meant to clean up the catchlights a bit? Perhaps make them smaller? The softbox was pretty close due to space issues and the catch lights are Huge! Good call!
You caught some great expressions, and the exposures are excellent. I too however find the fingers in 1 a big distraction. Also the large rectangular catch lights really detract from the shot as well.
Edit: I replied before reading the responses, sorry for the repeats on everything.
