Based on my own genealogical research, the trend I typically saw was 6-8 kids, between 18 and early 30s, about 20% of which died. Plus consider that some of those will be sons, and some daughters never become mothers, 25 is pretty spot on for the average age for a mother-to-mother generational gap.
Yes abd the field of genealogy, the size of a generation is given as 25 years. I believe specialists of genealogy who had to defined this metric did think about the way couple had kids in the past.
