Pumping and mason jars - did you buy 8oz, 4oz or one large jar? Which size do you use?

Anonymous
Tell me your routine. I purchased multiple 8oz for freezing but now I’m reading where many women use one large single jar and pour during the day. Please share which size.

Why would you do this vs. the bottles that come with the pump?

You’re going to freeze the mason jars? Why?

Freezing in bottles and jars never worked for me. They take up a lot of freezer space and would take 1+ days to thaw in the fridge. Lay flat bags in 2oz portions is what yo want, OP. Believe me.

Yeah I used 8oz mason jars for storing milk I pumped at work, but typically used the milk for the next day at daycare. If I had any leftover, I’d freeze in silicone ice cube trays. You want something that will defrost quicker than a large mason far.

This is what I did as well — except I froze in 3oz increments. A freezer ziploc works too. But the key is to freeze them flat as it makes thawing process much quicker.

I have never heard of using mason jars!

I thought that you were never supposed to freeze glass? I tried freezing broth in reusable milk jugs and they shattered while defrosting.

Definitely don't do a large jar, it will never defrost. If you must do jars, go with small quantities; I would do 4 oz personally. But the Honeysuckle bags are best.

Also remember that the more you transfer, the more you lose as residue on the old container. So pump into the bottle you will use if at all possible, and otherwise into a container you'll only transfer once. Is there a drinking nipple attachment for mason jars?

If you’re trying to freeze to build up a supply use bags unless you have the world’s biggest freezer. If you’re going to use a large container for pouring from during the day just be aware that you won’t be able to pour fresh milk into milk that’s already cold in the fridge, so you’ll either need multiple smaller containers or to refrigerate the containers you just pumped into to get the milk cold before transferring to the larger container. I just bought 3 sets of the bottles you pump into to make life easier and it’s working great. Anything I freeze I use Medela bags (also, do your research on bags, you’re *technically* not supposed to use regular ziplock for storing breast milk).

Great idea, I didn't think of that. I guess you should use what your baby will drink in one sitting. So usually 4oz as a small baby and 8 oz for a bigger baby.

If you're trying to avoid plastic, why not stainless steel? With glass you may have to worry about lead, unless you are totally confident in the manufacturer. Always something...

I've always frozen 6oz amounts.

And people- they make freezable large mouth mason jars!!

If you're looking to not use plastic, why not just feed the baby fresh? I only froze about 100oz or so as a backup and fed my baby fresh daily. I would pump into the bottles she'd eat the next day.

I pumped directly into the little freezer bags, 3-4 ounces per bag. Lay them flat to freeze, then "file" them in the ice cube bin, oldest in front.

My baby never drank more than 4-5 ounces in one sitting. The composition of breast milk changes over time, so babies often don't need to eat more. 4 ounce portions work well.

And the bigger the container, the longer it takes to thaw.

Pumping into a mason jar?!!! What kind of pinterest inspired nonsense is this? Honestly I thought I had seen everything. OP, are you ok?
