Baby fell asleep while drinking her milk! How long can breastmilk sit in an air-conditioned room before it spoils?

I believe most tins would have it stated on the tins; once baby has contact with the milk, dispose it after 1 hour. 2 hours if baby has no contact with the milk.

Only an hour if she has already started drinking from the bottle!

It should be consumed within 1 hour in room temperature.

thanks
