Ask an Expert: Establishing the Freezer Stash

By Nancy Mohrbacher, IBCLC, FILCA

Fan Question:

“I’m trying to establish a pumping routine to have a milk stash. My daughter is a month old and I have only pumped a few times. Every time I do, she drinks my pumped milk sometime that day because I’m low after I pump. Every time I think about pumping I worry that she will need the milk, so I don’t and then I leak lol. Need some advice as to how to establish a good pumping routine and have a good stash….thanks”

You’re not alone! Here are some tips to help you build your stash. Most women pump more milk in the morning than in the afternoon and evening. A good time to pump to store is usually 30 to 60 minutes after the first morning nursing that you’re up for the day. If your milk yield is average, you should expect to pump about half a feeding, which for a one- to six-month-old baby is about 1.5 to 2 oz. If you’re an exception to this rule of thumb, pump whenever you get the best results. Keep in mind, too, that even if your baby wants to breastfeed soon after you pump, rather than giving her your pumped milk, you can just keep breastfeeding, moving her back and forth from breast to breast several times until she’s satisfied. Unlike a bottle, your breasts are never empty. The unused breast produces milk while baby is on the other breast.  To learn more, read “How Much Milk Should You Expect to Pump” at: http://www.nancymohrbacher.com/blog/2012/11/27/how-much-milk-should-you-expect-to-pump.html.

  1. I pump about 3 times a day. In the morning, around 3, and at night before bed. As the day goes by, I only pump around 2-3oz out of each breast, compared to in the morning where I can now pump about 6-8oz out of one breast. I pump while my baby is on my other breast. When he unlatches or needs a burp, I do so. Then switch him to the other side I just pumped. This way he gets all my hind milk which is the fatty milk and makes him very full and satisfied. Then by the time he is done eating, I am done pumping, and I have a happy sleepy baby. I don’t feed him the milk I just pumped because my breast just make more since they are fully emptied. I freeze 6oz in each breast milk storage bag and deep freeze it so it lasts longer. This has helped so much get a great freezer supply, to where I am actually getting my own 7cu. freezer now! My baby is 3 months and still have not had any formula! I plan to pump and continue to breastfeed when I return back to work on the 20th! Knowing my baby is getting the best food possible by my body, makes me so happy! Breast milk is best!
