Can you re-warm breastmilk?

"... If the milk is warmed up but not used, it is OK to reheat the milk once. But the more you reheat the more you decrease some of the valuable immunologic properties of the milk..."

"...Based on this study, which admittedly needs to be done on a larger scale, it would seem to me that expressed breast milk, fed to the baby, partially consumed, and then refrigerated, could be used for one more feeding no more than four hours later. That's probably fairly conservative. One of the best tests of whether the milk is spoiled is to do what you do with cow's milk: Smell it and taste it!"

Breastmilk can safely stand at room temperature for 6 to 8 hours and need not be discarded if the first feeding attempt is incomplete. In contrast, formula must be refrigerated and discarded after the first feeding attempt because it contains no antibodies or infection protection factors.

Others have given you some great links to storage & usage guidelines, which I know you'll find helpful.. I wanted to suggest that, if your baby doesn't consistently drink the same amount from her bottles, try giving her only 2 oz. at a time, to avoid waste. You can always warm up a little more if she's still hungry, that way.

Also, if you are normally using your stored breastmilk within a week, it does NOT have to be frozen; only refridgerated. This will drastically reduce the number of antibodies and other properties that are damaged/destroyed during the freezing/thawing process, leaving the milk more "alive" for your baby's benefit. :)

Best of luck!

Yes.

Remember that breastmilk is different than formula due to the antibodies that are present.

ETA:

Never warm it in a microwave. That can damage some of the good properties of the milk and also cause hot spots which could scald baby. Better to let it float in a bowl of hot water or warm it under hot running water in the sink.

If milk will be used within 7 days, no need to freeze it. (Freezing and thawing can also break down some of the properties of the milk. Still better than formula though.) Just store it in the back of the fridge after pumping if you'll use it within a week.

You are not supposed to. I breastfeed, and pump occasionally, and I've been told that once they have eaten on a bottle, whether it is breastmilk or formula, you should throw it away if they don't finish it. I guess if small amounts of saliva and bacteria get in it from eating, it can cause bacteria to grow.

Don't warm it in the microwave, rather put the bottle in a pan of warm water to slowly warm it. That way you can re warm it, and it won't kill the good enzymes in it.

Did it with both my kiddos

I wouldn't. What I would do is put the bottle of milk in jug of boiling water to keep it warm. Keep for an hour, if you haven't used it by then throw away.

no u shouldnt. when u microwave or warm up ur breastmilk... all the good things that are in the mother's milk vanishes and its not as benefitial to the baby. :) so i suggest u shouldnt

We did with no ill effects to our child.

You really shouldnt b/c of bacteria growth

Not recommended. It can spoil the milk.
