Can you mix different days breastmilk?

[Kate3150]

I pump a bit each day.. about 3oz just incase hubby needs to do a feed.
My question is can I mix today and yesterday’s in one bottle as I’m collecting bits here and there but would like to put it all together TIA X

Yes you can but it might be best to keep in smaller portions in case your lo doesnt drink a larger amount in 1 sitting.

I did, it was fine

Yes but it needs to be the same temperature first e.g. fridge cold before you mix them
