I think it's funny when people still say that Sokka and Toph had Lin. That would mean that Tenzin and Lin were cousins and they dated. Not saying anything about the morality of that, just saying that Nickolodeon would be aware of that and would not allow anything suggesting that to air to stop the angry mobs. 
Toph obviously never had a man. She's Toph, she can make a baby herself.
Or maybe Toph invented a new form of Earthbending where she just made a rock into a baby shape and turned it into a human. Babybending.
