Stop milking her. Put her in a pen where she won't do much harm to her udder (like bruising it in some way), and she will decrease her milk flow to nothing after a few weeks. Also consider putting her on lower quality feed and/or pasture to help speed up the drying up process.
So they can they can give milk to their calf and so they can give birth.
You don't have to have dairy cows if you are not wanting to make money off of producing milk or want to have milk for yourself and your family. The only time you have to have dairy cows is if you are getting into a dairy operation.
Cows finish lactation when they are being dried off; i.e., when they're weaned form their calves, or when the dairy farmer has to dry them off to give them rest before calving in two-months' time.

Dairy cows
Milk is the most important product that dairy cows have to offer, and it has become sort of a necessity for dairy farmers to being breeding heifers as soon as they are able to. A cow cannot produce milk until after calving or parturition (or giving birth). So at around two years of age, the heifers are bred to give birth and officially become dairy cows that can produce milk. Dairy cows will reach its milk production peak at around 40 to 60 days after giving birth. After that, production will steadily decrease. Eventually the milking will cease when the cow is dried off after about 305 days. The dairy cow can calve again a year after her first birth. For high production cows, though, it is viewed that 13 or 14 month cycles is appropriate because high production cows are more difficult to breed.
