I to agree that just because a mom is nursing doesnt mean that she cant be doing something productive. She could be a teacher or sitter for the other children. the villagers could find a way to make a sling/pack so that she could continue to work!
Also concerning families: I would like to see "couples" & "families". this could be achieved by once breeding a couple their clothing changes to matching colors and once the baby is 2 its clothes would be the same color as the parents.
just a thought:)
