A baby cow is called a calf, and the gestational period for a female calf is longer than a boy's calf. All newborn cows are born with fully developed bodies and organs, and the mother helps them grow to be healthy. Just after a calf is born, it begins to make moo sounds, which is how it communicates with their mother.
Like many other animals, the baby cow can stand and walk on their own very quickly after they are born. The mother cow is filled with pride for her young baby cow, and a mother cow protects and takes very good care of their young.
Cows will often celebrate when another cow is born, and all the adult cows surround the calf and watch over it, keeping it safe and warm. Some people keep cows as pets if they have at least an acre of land for the cow to live. The best way is to have the cow outside until it is night, then it goes into a barn.
