But don't have it in a bottle - it expands on freezing and glass will shatter.
I often put a pint in the freezer when I go on holiday, so that I've got some milk when I get back. Thawing can be speeded up by GENTLE use of a saucepan of hot water, or short bursts of microwaves. (You don't want to cook it!)
For the past 12 years, we've always frozen 5 x 2 li Pet's, fortnightly , 1 li left get next out to thaw, this weather it's best to take a jugful at a time from fridge.

I wouldn't have thought so. In days of old, what happened when the milkman delivered your milk just after you've left for work & it was frozen when you got home at night. You wouldn't have thrown it away, just thawed it out & drank it. Nobody died, well not that I know of!
