Do you mean more like surrogacy, or more like teacher/personal tutor?

The former… I'm told is medically inadvisable over 5 births, even if humans used to have 10 in the hope of 2 surviving to adulthood. But that may be confounding variables given 5+ is unusual.

The latter is, I think, a good idea that people will object to actually paying for — "teacher" is not as highly respected a profession as it ought to be.
