Quick Summary

Weaning is the biological process by which young mammals are gradually accustomed to accepting an adult diet, transitioning away from milk. This process involves the withdrawal of access to milk from the mother's mammary glands. Suckling, the drawing of milk from the nipple, is the primary method of nourishment for newborn mammals. The duration of suckling varies greatly among species, from a few days in rodents to up to two years in walruses. Milk composition can change during this period to meet the evolving nutritional needs of the young. Weaning is often initiated by the mother animal through behaviors like aggression when the young attempt to nurse. When suckling ceases, lactation, or milk production, also stops.1
