How do you start lactation without getting pregnant?

Lots and lots of stimulation of the nipple from your hands and/or a partners mouth. When you stimulate the nipple it sends a hormone to your brain telling your body to produce milk. You can also purchase a breast pump off of the Internet or rent one from a lactation consultant at a hospital. Although they aren't necessary, breast pumps are good for stimulation and the expressing of the milk after it comes in. You can take an herb called fenugreek, vitamin B, and brewer's yeast which you can find in your local health food store/ vitamin cottage. You may also take a drug called domperidone or "motillium" which I wouldn't recommend because it's not natural and has harsh Side effects. Eating oatmeal and flax seeds help produce more milk; in fact there are even oatmeal cookies that you can make that include brewers yeast and flax seeds which you can eat to help increase milk flow, I believe the recipie is called "breast milk cookies". Also make sure you drink plenty of water ( 9 to 10 glasses) every day. You must also have a good mindset and be confident. Believing in your ability to make milk mentally and physically is important when trying to lactate. Never give up! Have fun and good luck!!
