Where do cows keep their babies?

Answer 1

During the gestation period, cows keep their babies in the uterus, otherwise called the womb to allow the calf to grow until it is ready to be born into the world.

However, if you are referring to where cows keep their babies while they're away grazing, they keep them hidden in bushes or in grass that is tall enough to conceal them from predators. This is not unfamiliar to other ungulates that do the same like deer, elk and moose do with their young offspring.
