I find M&B, taking into account that it is a fictional non-fantasy video game, is very realistic. You might think that women warriors are unrealistic, but it is possible, there were many cultures where women had their place, there were heavily matriarch societys etc... M&B doesn't try to completely replicate the medieval ages, it's obviuos.
About the child having, maybe you could adopt a child (like 16 years old) into your family? I guess that's a suggestion for a module
