How to care for young Polar bears

Have you ever considered this topic? well, looking at nature, one thing borders me;which is, how these creatures survive. So, I decided to search for some facts about them. Here are some of them:
1. Nursing.

• Female polar bears have four mammary glands. Mothers nurse their cubs in a sitting position, or lying down on their side or back.

• During their first few weeks of life, polar bear cubs nurse most of the time and stay close to their mother to keep warm.
• For the next three or four months the cubs nurse as often as six times a day. The length and number of nursing bouts gradually decreases as the cubs grow older.
• Mother polar bears nurse their cubs for as long as 30 months. Some cubs stop nursing as young as 18 months of age, but remain with their mothers for survival until they are 30 months old.
• The average fat content of polar bear milk is 33%, similar to the milkfat of other marine mammals.


2. Mother polar bears are extremely protective of their young, even risking their own lives in their cubs' defense.
