I was asked just today, actually, about how much juice and milk we go through in any given week. The ladies I was with made the natural assumption that we must go through a ton because of our family size. They were shocked to discover that we only go through about 2 gallons of milk/1 large jug of juice a week. That's including both consumption and baking.
How do we do it?
I've always cut juice almost in half with water ever since we started having children. We didn't have a whole lot of money when we first got married and starting having babies so I scrimped wherever I could. After a while, it became habit. Our kids don't know the difference because it's all they've ever known.
It's only been recently that I've started diluting our milk. I got the idea from New Life on a Homestead. At our Aldi store, the price for 2% (our usual) is identical to the price of whole/vitamin D milk (approx. $2.09/gallon). So I simply started purchasing vitamin D milk and diluting it (almost in half) for both consumption and baking purposes. NO ONE'S noticed the difference!
