I think the lighting is good, although I think I'd like to see a touch more contrast in it.
Number 1 - I think the baby looks a bit distressed. And might have worked better with Mum's shoulder bare. I think I would either shoot from further back or crop in tighter. Don't like the way baby's arm is chopped off at the wrist.
Number 2 - best of the bunch for me. Would be nice to see catch lights in baby's eyes and maybe a bit more light on baby's forehead.
Number 3 - agree the watch is distracting. The lighting here is good in my opinion, if a little to intense on the arm.
Overall a nice set and I'd expect the parents to be very pleased.
