Other than the niece, why not drop juice? I have coffee in the am, and water the rest of the day. I haven't had anything to drink but water (and coffee) in over a year and a half. I did have one glass of unsweetened tea
, but that's also very inexpensive to make.
Most juices have a lot of sugar, and not many nutrients.
(my kids get apple juice, but it's watered down by at least 50% to keep sugars down)
Here's a great, simple recipe. Get the hamburger lean in bulk (our 'fancy' grocery has lean ground beef inexpensive in bulk), then utilize rest of veggies in other meals. I think this is tasty for being so easy. My kids ate it too!
