Its fine to combine milks as long as you use the oldest one as the use by date. Also you can re-heat it but it needs to be re-used within 6 hours from taking it from the fridge the first time (if that makes sense?)
Thanks ladies :)
Also, there seem to be different views about whether you can re-use breast milk that has been heated once. Say you heat a bottle and your baby doesn't finish it.. do you think it's okay to reheat it a few hours later? Should you put it back in the fridge in between?
Yes, definitely!
Just remember to measure maximum storage time from the oldest milk (if for example in the 2nd situation it was for further storage, not for feeding immediately).
You can also add freshly-expressed milk to already-frozen milk - you just need to cool the new milk first in the fridge.

What is the general view on combining milk expressed at different times?
1. If I express 3 times a day, for example, and after the first time, i store the milk in the fridge, can I add the milk that I express the second time to the first bottle and add the third lot to that as well?
2. If I have a bottle of say 4oz from 2 days ago in the fridge and want to add another 2 oz to it for a feed and this 2 oz has been expressed today, can I add it safely for the feed?
