Like many new dads, Sabastion Sparks knew parenting would come with serious challenges. But most new dads didn't give birth to their child. They didn't breastfeed them. And they don't endure glares from strangers when they go shopping with their wife and their toddler son. Sabastion, 24, is a transgender man who lives with his wife Angel in suburban Atlanta. Assigned the female gender at birth, he began transitioning five years ago . It's a process that felt more complete last month when he had surgery to remove his breasts.
