I was going to suggest information about family trees, but that might turn out to be too creepy (all the inbreeding.) I do think that the women should be able to hire babysitters or at least turn the kids over to some male villager for a while. It's hard to explain to my 7 yr old son why only the mommies stop working to take care of the kids (almost worse than explaining why they are going inside the huts and coming out with babies.)
