Do a baby's nails grow while it is in the womb? Or is that somehow inhibited?

Yes! and the rate of growth is much faster than adults;  the nail beds first appear at 12 weeks gestation and by 20 weeks they can be seen as translucent layer-similar to fetus skin-, the formation of nails is pre-genetically determined and ends 34w for fingernails and 38w for toenails at that time they become hard and slightly sharp, after birth the nails can be trimmed and they grow again as normal.
