Would recommend fo freeze milk immediately in freezer if possible, because the temperature in the fridge can fluctuate quite a bit, depending on how many things are inside, and where you place your milk, as well as how often the fridge is opened. Frozen milk is recommended to be kept for at most 3 months. Also keep away from raw food.
Yes, i do that sometimes, after a day or in the fridge. 3months in separate freezer compartment of the refrigerator, 6mths in deep freezer
By freezing it, it loses antibodies. So if possible, use it up first if possible.
I try not to do that..
