We usually had 3-6 milk cows and my parents sold the milk and cream. I started milking cows by hand when I was about 8 or 9. Did it until I was about 15 or so and gladly took on other chores like feeding to get out of milking. I always swore I'd never milk a cow again and haven't. I'd stop drinking milk if it meant having to milk a cow to get it.
