Frozen milk questions


Okay, I was under the impression that if I took milk from the freezer, put it into the fridge and let it thaw in the fringe (not warmed!). I had to use that milk within 24hr.

Ive been taking frozen milk to the daycare, they keep it in a fridge, my son doesn't always eat all the milk I send with him. So they keep it. I'm worried that the milk he's drinking has been thawed for days.

Is that safe? Maybe I was wrong about the 24hr thing? I'm paranoid 🤷🏻‍♀️
