recently, i have been pumping about 2.5 ozs at a time. then i put it in the fridge. so when i want to pump again, can i pump into that 2.5 oz bottle or a new one and keep them separate? and in the case, can i put the milk in the fridge for say, a week, dont use it, then freeze it?

so my question then becomes if i use the bags, which i cant pump into, i only get 2 oz or so, i would need to defrost numerous bags for one bottle?

Actually...you can pump directly into the bags, I do. I just place the bag around the end of the cup (where the valve is) and pump directly into it 



Yes you do need to sometimes defrost more than one bag per bottle. It is important to measure and label before you freeze it so you know how much. Although it may seem like a pain to defrost more than one it actually cuts back on waste because you can feed them a smaller amount and if they are still hungry you can add more. If at that particular feeding they weren't as hungry you don't waste a large pumped bag of milk.



Or you can pump the 2oz (or so) refrigerate it, next time you pump refrigerate that milk. Once they are at the same temp in the fridge - combine them - then freeze that way you will have 4oz. of milk per bag. I have been told you can mix different days of pumped milk as long as they are not over 3 days old and as long as they are the same temp. You almost have to because you usually need more milk per feeding than you can pump at once it shouldn't matter if you mix it before you freeze it or after in the bottle.

i personally felt safe keeping milk in the fridge up to 3 days tops, then freezing. i also mixed the days, but the 3day limit was always counted to the first amount of milk in the container. Every book i read was different. one even said keeping milk room temp was okay for 10 hrs. i personally wouldnt try that one!!! Also, i only kept it in the freezer for 3mos.

Also when I saw a local lactation consultant she imformed me that it is best to combine pumped milk at the same temperature. So if you want to combine fresh pumped milk with refrigerated you should refrigerate the fresh stuff before you combine.....ahhh, so many rules!!!!





Yes, I was told that too.  Also, one thing I used to do to try to increase my milk supply while the baby was in the NICU was keep the milk at room temperature for a half hour or up to an hour and pump on top of that...kind of like a baby does when they have a growth spurt.

Here are the guidelines from babycenter.com....



It is generally accepted that you can refrigerate breast milk for three to five days and freeze it for three to six months.
Don't freeze milk you plan to use within three to five days because freezing destroys some of the antibodies. (However, frozen breast milk is still healthier than formula). You can keep milk that's been frozen and thawed in the refrigerator for up to 24 hours, but don't refreeze it.

Breast milk contains live antibodies that kill bacteria. Since bacteria is what causes milk to spoil, the antibodies in breast milk will keep it fresh longer than formula or processed milk.

But in reality there are no absolute guidelines for breast milk storage. The many variables include the type of freezer you have and how well it works. A separate deep freezer unit will keep milk fresh longer because you generally don't open it as frequently as you do a freezer / refrigerator unit.



Also when I saw a local lactation consultant she imformed me that it is best to combine pumped milk at the same temperature. So if you want to combine fresh pumped milk with refrigerated you should refrigerate the fresh stuff before you combine.....ahhh, so many rules!!!!

I personally had read that you could refrigerate milk for 1 week. I do only mix from the same day. Regular freezer a month and a deep freezer 2-3 months.



My son is only 2 1/2 months and I am still at home, so I don't pump a ton, but I have given him one week old pumped milk and he is just fine.

my midwife said to keep breastmilk in the fridge no longer than 3 days and if it's not used by then to toss it...she also discouraged mixing milk from different days. I'd say if it's done before the 3 days it's okay to freeze, but i'd keep the milk from each day separate. I used the medela bags for my milk and they were so much more convenient, i didn't always run out of bottles. Plus they're easier to store in the freezer.

wow! thanks for your feedback.  so many rules, so confusing.  my pump instructions say room temp up to 10 hours and fridge up to 8 days.  well, it definitely helps me with my questions!!!  thanks so much!





Wow I would definatly not follow those guide lines!! Room temp freshly express milk is usually ok up to 4 hours, and thawed 2hours max. Storage in the fride should be no longer than 24 hours if fresh then freeze it... but don't refreeze your milk.

Check out la leche league's restrictions - they say you can leave milk in the fridge 8 days, and at room temperature for 10 hours. My daughter was a preemie, and in the NICU they keep milk in the fridge 24 hours, at room temp for 4 hours.
At home I started going by something in between and had no problem, nor with my first.
However, no, you really aren't supposed to pump fresh milk on top of the refrigerated milk. And NEVER pump fresh milk/pour fresh milk onto frozen milk because it thaws and refreezes. I also was told in the NICU by one young nurse with no kids that I couldn't put milk in the fridge for a while and then freeze it. However, another nurse who pumped for 11 months told me it's fine to do that, as long as it is within the time limits, and you don't restart the time each time you switch storage methods (i.e., you don't act as if it were new if you put it in the freezer after 6 days...still only good for 1-2 or 3-4 months depending on freezer).
I also learned in the NICU, the biggest issues with milk are people trying to refeed a bottle that the baby already drank off of (later in the day) and trying to refreeze milk/put fresh milk on top of frozen milk. Once you start feeding off of a bottle, you have about 1 hour for the baby to eat. Then it's trash...:( or at least that is what I learned in the NICU.
Also, just as an afterthought...don't microwave breastmilk, it breaks stuff down and is not good! it's not just a hot spot issue like formula.
Last thing that was helpful for me to find out was that when you freeze milk, it kills some of the great goodies in there. So I try to freeze for emergency use, and keep using my fresh milk on a regular basis - not using the frozen milk, then freezing the new milk, as I was originally.
Sorry this is so disjointed, hope it helps. good luck pumping! I managed to do it for 6 weeks without my baby home :( but while she's home, I can't seem to manage it except for a little here and there (hence my thread regarding baby Nursing All the Time). I will start again when I go back to work in February...

I read that when you freeze it you can top it up as long as the amount you put in is less than the amount already frozen.Is this true? How long does it take to defrost in fridge?

From what I read a few years ago, you should only keep milk in the fridge for 24 hours max. If you're planning to keep it longer than that, it should go into the freezer.

I would think that it would be fine to mix milk from the same day, but I wouldn't mix milk from two separate days. Everything I've ever read has told me not to mix from different days. Anyone else have any more scientific recommendations?
