Do you usually scan live babies or something? I've never heard of this type of thing for the living or for the deceased.
We did occasionally scan children and toddlers as part of a 3D family photo product we offered. Infants usually were a bit too squirmy. In the little statue we'd make it would look like the mother was holding a swaddled bee larva. One of our machines (it was a structured light scanner) had like 50 cameras and did the image capture in one shot. It was actually powered by Raspberry Pi 2s.
We also worked with the cosplay scene in that using our handheld structured light scanner we could get pretty good face and body scans. Instead of doing live castings of hands, faces etc. we could 3D scan the subject and then either print that body part on a 3D printer on which makeup prosthetics etc. could be sculpted, or it could be used to model costume parts in-software.
We had floated the idea of doing death masks. Occasionally for various reasons they cast molds of the deceased, and again we could do this faster and with less mess. And precisely one person also had this idea.
Presumably, a live baby would move way too much for photogrammetry to be useful.
It's exactly forbthat reason that Revopoint (I shit you not) recommends you catch 'em while they're asleep. Same for pets.
