OH I LOVE MILK!
If I had a cow I'd lay under her all day long. I would udderly be in heaven.
Freezing milk is fine. Thawing it can suck. Let it thaw completely before drinking. My kids would keep going into the fridge and pouring out whatever is not still ice all day then what's left is all watered down and pooey.
I used to thaw it just by putting the jug in my dish drain rack by the sink for a few hours and shake it every now and then until I couldn't hear the ice bang the sides of the jug anymore. The jug will sweat profusely as it thaws so this ended up being a win/win anyhow.
