I have given this a lot of thought and I have read all the posts of what others considered their ideal tribe. After considering everything; a tribe of nursing mothers would definitely be challenging but my luck would be the 5 nursing mothers would all have female children. A tribe of children also would be very challenging also but could be disasterous which is something I don't want at the beginning.

So I think what I will try is this:

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 would look carefully at likes and dislikes looking for ones that like things like medicine, herbs, work, running, etc.
And I would look for dislikes of laundry, play, jokes etc.

I would work the 2 oldest back and forth between farming research and building the 1st hut if it was necessary and would use the kids to get all the mushrooms and collectibles that I could get as they do seem to appear fast and furious at the beginning. This may not be the best way to go but hopefully by starting out with the younger ones I will be able to accomplish a great deal before the first ones die off. After all longevity is a problem in the early stages of the game. I think it will be interesting to post how my ideal tribe is doing and read how others ideal tribes are working as well.
