unfinished milk

Pretty sure the standard is 2 hours from when you start the bottle till needing discard. BUT I've also seen qualified people speak on how no major changes in bacteria happen at room temp within the first 24 hours, so of course, an old 12 hour bottle should be tossed regardless but personally. My baby feeds every 2-4 hours and if he leaves an oz, I'll refrigerate and add to his next bottle to finish. I feel the most important part is how you clean your bottles

I'm sure once baby's started feeding it needs to be used in that hour then needs throwing out. they can be left for 2 hours if they've not had any. if you were to put an unfinished bottle in the fridge I think bacteria can grow in it quicker so it's definitely not a good idea but if it's untouched they can be in there for 24 hours x

(don't quote me but this is what I've been told)

It depends on if you are formula feeding or if it's breast milk because there is a difference

I think formula was an hour and thawed breastmilk is two and freshly expressed breastmilk is four.

I do a smell test. I’ve even done a taste test lol.

I believe freshly pumped milk lasts 4 hrs but milk that was frozen and then thawed has to be drank within 2 hrs I think.. I got that info from something Babylist sent me in their care box.
