A cow will often make it's calf stop nursing by the time it's around 10 months of age. Most producers have the calves stop earlier though, like around 3 to 6 months of age, to prevent the calf from "pulling down" his mother any more than she needs to be before she calves again.
Disease or a blockage in the gut will cause a calf to stop eating. This is something you need to take up with your local large animal veterinarian immediately if you wish to have a hope of saving the calf.
First make sure if the calf is indeed nursing from the wrong cow. Then separate the calf and his mother into a different pen or pasture and let them stay in there for a few weeks. Make sure it's just the pair that's in there and there's no other cows in there with them that the calf may decide to latch onto.

No because if they did the babies they are nursing would most likely die of starvation.
