If it helps Laura I think there's a few improvements that could be made, the carpet material is quite busy and distracts a little in the first two shots, also get people to take off their watches as they too can look out of place. A closer crop on the first would isolate the key elements of that scene.
I can see the shot you were going for in 2 but would have been better with the babies feet in a similar position, difficult, almost impossible I know with kids!
With 3 the focus is on the dolls feet which IMO doesn't work, always go for the child's eyes or if you want to shoot the doll, the dolls eyes.
4 has a nice composition, the kid just looks a little miserable!
HTH
