Milk brother or milk brothers usually refers to two people of different parentage, who as infants were nursed at the same time by the same woman. That woman is likely a wet nurse, though she may be the mother of one of the infants.
King Viserys I Targaryen ordered his son Daeron and his grandson Jacaerys Velaryon to be nursed by the same wet nurse, because he hoped to prevent enmity between them by raising them as milk brothers. Unfortunately, the plan was unsuccessful.
A Storm of Swords
In the riverlands, Edric Dayne tells Arya Stark that her half-brother Jon Snow is his milk brother.[N 1] Edric explains that his mother did not have enough milk for him when he was born, so he had to be nursed by Wylla, a wet nurse at Starfall. When Arya asks who Wylla is, Edric replies that she is Jon's mother.
