Breast Milk Freezer Storage: Your Question Answered

Breast Milk Freezer Storage Your Questions AnsweredDear Rando,

I’ve got some questions for you.  I am preparing to go back to work and my plan is to pump while I am at work.  I have a ton of questions on breast milk freezer storage – how to pump at work, how can I store it, can I freeze it?


Confused and Overwhelmed

Dear Confused and Overwhelmed,

First, thanks for writing to me.  You are my official first write-in question posting here on the

I’d love to talk to you about storing your pumped milk and what I am going to tell you is the process that I used myself to store my own.

A little back story for ya. I went back to work when my daughter was 8 weeks old. I was dead set on pumping, even though I could have just used formula. I mean, I am sure you are aware of all the benefits for breastfeeding, and that’s great, but I’ll tell you a secret to why I pumped. It was because I was able to take my breaks without interruption at work. Silly right? Well, in my job, I was always interrupted, so those 15 minute breaks behind a locked door were heaven.

The pump I used was a Medela Pump in Style Advance.  I pumped into Dr. Brown’s bottles because they fit my pump attachments and were more than 6 oz., and I liked the leeway. Once I was done pumping, I would pour the milk into Playtex drop-in because those were the bottles my daughter liked.

When my break was over, I would put the bottles in my mini fridge at my desk, and put all my pump parts in a freezer zip lock bag and I would put all that in my fridge too so I wouldn’t have to wash my parts in between pumps.

Now on Friday, I would pump and pour my milk into Lansinoh milk bags. Everything went back into the fridge and when I got home, Friday’s milk would go in the freezer. My tip for freezing your milk is to lay it on its side in the back of your freezer. I recommend this way for a number of reasons. First, it stores better and you get more freezer space. And second, when you defrost it, it defrosts faster.

Well, Confused and Overwhelmed, I hope this helps. And I hope this works out for you. The only other suggestion I have for you: bring your kindle with you on your breaks so that you can catch up on your reading!

Happy pumping,
Rando, the boob whisperer
