Can milk be frozen?

I feel kind of dumb for asking, but we were out of milk and bread so I went to the store to buy some, and when I came home I saw that my dad also went to the store and got some. I should have checked with him first, and now we have 2 gallons of milk and 2 loaves of bread (it's wheat bread, and he's the only one who eats it). So, is there anyway to preserve the milk and/or bread for a while? Can milk be frozen?
