Unfinished milk
Fri, 02-10-2012 - 4:27pm
If my baby does not finish his bottle how long can I save the leftover milk to give to him later?? Can it be at room temp or do I have to put it in the fridge?

I was told I could NOT save it any amount of time, but I have read on some post here that I can save it and use it later? Which is right??

The problem with saving milk is that the bacteria in the baby's mouth contaminates the unused portion. I'm sure there are varied opinions, but I found the most comfortable route for me was to fill my daughter's bottles on the low side. Then I would give an extra ounce or two if she was still hungry. That way I did not risk reusing milk and also did not waste any. I didn't feel as compelled to be quite so careful once she was 8 or 10 months old or so. I'm not sure there is a "right" answer to this, in that people probably reuse and don't reuse, and I read somewhere that there weren't any documented cases of babies getting sick from reused breastmilk, but I always found I felt more confident being on the safe side.

personally, i rarely ever throw out breastmilk. if my daughter doesn't finish a bottle i put it in the fridge and rewarm one time at the next feeding, i let her finish that, then make a new fresh bottle of more milk to continue that feeding. an lc from the hospital where i delivered actually told me it would be fine for the next feeding. if it gets left out (and it's not freshly pumped) then i toss it after an hour or so if the baby is not interested in it. if it is leftover and stays in the fridge for more than 3 hours, then i toss it. i'm pretty sure if you use it for your next feeding you're fine. my first daughter survived this way ;)
