This bed is made by lining the bottom with shredded bark. During the birth, the female uses her large flat tail as a landing area or birthing mat. As each kit is born, the mother licks it clean. It can take two or three days for all the kits to be born. The newborn kits begin nursing from one of female's four nipples.
Beaver milk is quite thick and yellowish.
The young continue to nurse for six to ten weeks. The young beavers gradually learn to eat the same food as the adult beavers. After one year, the beavers are called yearlings and remain with the mother and father. The beavers are very social animals and live and work together on activities such as food gathering, dam building and tree cutting. At the age of two, the beavers reach sexual maturity, which means they are ready to mate.
