I don't think this would work without air.

Maybe it can. It's called cavitation.

Are fetal tongues strong enough to induce cavitation? Are fetal mouths strong enough not to be shredded by cavitation bubbles collapsing? AFAIK cavitation kills a ship's screw sooner or later.

Cavitation can develop with wide range of energies. In this case, I'm suggesting energy level sufficient to create an audible sonic click, but not high enough to rip infant's head off.
