Her advisers suggest she marry Hizdahr zo Loraq to bring peace, and she agrees, although she takes Daario as a lover. Hizdahr successfully negotiates an end to the violence and Daenerys marries him.
Originally Answered: Can daenerys not have babies? The answer is actually unclear. There's nothing in the show that suggests she couldn't have children. In the books she believes she can't due to Mirri Maz Duur saying this about when Drogo would return: When the sun rises in the west and sets in the east.
