Summarize this article in one sentence.
The most popular site is “Only The Breast,” which is a kind of Craigslist, but it’s exclusively for buying and selling breastmilk. Women can post free classified ads for their milk. Most women sell their milk for an average of $2.50 an ounce, though you can also sell in bulk.  Online milk communities generally have recommended standards for health, screening, storage, and transportation guidelines but do not police them. Babies need between 19 and 30 ounces of breast milk daily, so if you are able to produce 25 ounces of milk per day, you can make almost $23,000 a year by selling your milk. Most sites require you to be a member in order to post ads, and this helps keep those communities private and free from spam. When filling out your profile, include information that you would want to know if you were buying breast milk online. Ideas include your health, special dietary restrictions (gluten free, vegan, plant based, etc.), how long you have been producing milk, and how you store and transport your milk (milk packaged with dry ice is the best way). If you can, provide references from others who have purchased your breast milk. Because these sites aren’t as regulated as milk banks, setting yourself apart from the rest of the sellers is key to having a consistent business. This generally isn’t required by online milk communities, but it can go a long way in reassuring buyers that your milk is safe and that you are a responsible seller. Make an appointment with your doctor and explain what you are doing and they will be able to run a blood test and health screen for you. You can get these records and share them with potential buyers. If you are sharing your health records with someone, black out any personal identifying information, like your last name, address, and social security number. Because you are selling your milk yourself rather than letting it be processed through a milk bank, you need to essentially market your milk. Most moms with babies are looking for moms like themselves. You can share about your own baby’s health and include a few pictures to make the ad more personable (but keep it G rated—no topless pictures).  Explain in your ad how you package and deliver your milk. Are you requiring the buyer to pay for shipping? Do you freeze your milk and ship it overnight? Are you available for face-to-face transactions? If you have preferences about who you will or will not sell to, this is the place to clarify that. If you don’t want to sell to men, put this in your ad and be very clear. Write something like “Donation to a baby only. No adult wet nursing. No pictures. No videos.” Milk needs to be stored in sterile, individual bags. These bags need to be weighed and marked with the ounces. Put pumped milk into the fridge or freezer within 30 minutes of expressing. If you are delivering the milk in person, transport it in a cooler lined with ice. If you are overnighting it, use dry ice to package the milk.  Never top off your breast milk with other substances, even bovine milk. If this is consumed by a baby with a milk allergy, it can be life threatening.  Breast milk can be stored in the fridge for no more than 5 days and in the freezer for up to 2 weeks, so it is best to sell and transport it as quickly as possible. Individuals who are receiving the milk are responsible for the pasteurization process.
