(Relatively) urgent defrosted breastmilk question!

[MashNpeas]

I'm due out shortly and have one bottle of frozen expressed milk to leave with DH and baby.

Once defrosted and warmed slightly how long does it last? Does baby have to finish it within a certain time or can she come back to it within an hour / two?

Thanks!

Thanks @NoisePollution that's much clearer than all I'd found online. I shall go to the ball... ;)

6 hours fresh
6 days in the fridge
6 months in the freezer

Obviously these are the maximums, but an easy guideline from la leche league

Thanks @holidaylady it's more of a case of once I've defrosted and slightly warmed a bottle and baby has drunk half - how long is that bottle still good for?

6 hours max I'd say
Google your question and the words la leche league as they have all the up to date research on the latest guidelines

Thanks @KatnissMellark
