Ok I’m hearing diff answers: my day care throws out a breast milk bottle if heated once and not drank completely within two hours.

How many times can breast milk be reheated? Can I refrigerate and heat up again?? I’m so confused! I thought I could heat up twice and refrigerate for up to 5 days after the first heat up?? I am sick and tired of wasting breast milk at this daycare! They just threw out 5 ounces after I told them yesterday I’m struggling to keep up!

Edit- I pack 3 bottles each with 4 -5 ounces fresh every day as they requested and keep frozen bags there too if needed. I also bring a empty bottle if needed to be split, to minimize waste. They just like unthawing bags for a full bottle if needed which it never is and goes to waste. Very aggravating.
