1- male 14 with some skill in farming and preferably a runner
1- female 14 with some skill in research and preferable a runner
also
1- female 10 and if there are skills for children I would choose
some skill other than building
1- female 6 the same as above
1- male 2 the same as the other kids
I see your point, but if I were going to use this strategy I would just make the first 3 age 14, and then bring along a pair of 2 year olds. That would still leave me with 3 hands to accomplish the initial work, while the "kids" gathered mushies and other collectibles.
It would also still leave me 10 game years before I had to worry about growing the tribe. I can accomplish a lot with 3 workers (especially if 1 or 2 are runners) in 10 game years. By the time I needed to expand the tribe, the collectibles should have slowed appreciably. At least that's been my experience with the previous VV games.
