Pumping and Storing Human Milk

The Basics of Pumping
Wash your hands first
Wash your hands before pumping human milk, and then massage both breasts.
Start with a low suction
Pump both breasts at the same time, starting with low suction. Then increase to a comfortable pressure. If you can free up one of your hands, try compressing your breasts (squeeze softly and then let go, over and over) to get more milk out. Continue until your milk flow slows to a trickle.
Massage your breasts again, especially in areas that feel full.
Express into the pump’s bottle
Finish by hand expressing your milk into the pump’s bottle shield or pumping one breast at a time. Do whichever way you are able to express the most milk.
Your breasts make more milk than you will be able to pump, but it is important to pump regularly while you are away from your baby. It will keep up your milk supply.
Pumping shouldn’t hurt.
If you have pain or difficulty with pumping, ask the WIC office or a lactation professional for help.
If you have experienced an injury or infection from a breast pump, please report your breast pump issue to the FDA. This can help them to better understand the risks of breast pumps and potentially prevent problems from happening to others.

How to Store Human milk
Wash your hands before handling human milk.
You can store human milk in a plastic or glass bottle with a screw-on lid or in sterile zip-seal human milk storage bags. You can find these in the baby section of most grocery stores.
Label the containers with the date the milk was pumped and your baby's name. This is helpful if your baby goes to child care where there is more than one infant or if more than one nursing parent is pumping at work.
Cool down the human milk you pump as soon as possible. You can store it in a refrigerator or in a cooler with ice packs. The milk can also be frozen if you aren't going to use it right away.
Store human milk in amounts that you use for a normal feeding. Since you can't re-freeze human milk, you may want to start by storing about 2 to 4 ounces per bottle or bag. You want to use every drop of your BEST!
