You can deduce that each man only has one wife by trying to convince your wife that if you had a child with another woman, that child is hers as well, and see how that goes.

quoting nevent1q…2a2r

Though even if a man has 7 wives, all the children are his, while only each woman's own children are hers.

If a man has 7 wives and 7 children, each wife would only have one child. But it's stated that each wife has 7 children. So each man can only have one wife.
