Milk brother or milk brothers usually refers to two infants of different parents who were nursed simultaneously by the same woman. Twelve year-old Edric Dayne told Arya Stark that Jon Snow was his milk brother, but Edric was stretching the term a little as Jon is four years older than him, and had long been parted from Wylla's breasts by the time Edric came along.
Known milk brothers
- Edric Dayne and Jon Snow (both nursed by Wylla, Edric because his mother did not have enough milk for him when he was born)
- Arianne Martell and Garin of the Orphans (both nursed by Garin's mother)
- Gilly's son, and Mance Rayder and Dalla's son Aemon Steelsong (both nursed by Gilly because Dalla had died in childbirth)
- Jacaerys Velaryon and Daeron Targaryen (both nursed by the same wet nurse because King Viserys wanted them to be raised together without emnity)
