Adding my comment to this thread as well:

Yes!!! Also, kids are really really vulnerable! I’d follow up your “so how many kids then?” with “and how many dead?” Also, if one assumes all babies and toddlers are nursing if able (which one hella should ) natural child spacing is about two years apart per sexually active and fertile woman, with some women naturally going to four years between births and others going to one year. Given a life expectancy of 60 and an onset of menarche at 12 and menopause at 40, and first birth at 16, that’s 10-14 reasonably possible children per bearing parent, providing for survival of childbirth and complications in the first six months, which drops both surviving children and bearing mothers by as much as 10% easy.

In other shorter words: heck yes this.
