I love juice boxes! The pouches aren't nearly as good, though, I've noticed. My favorite is probably the mandarin orange types. I don't like it much when I feel more adult.
I like juice boxes, I just don't like the juice in them. I like fresh juice with pulp. I have a running water bottle with a squeezy valve thingy, and I really like sucking water out of it, maybe because it's a lot like a sippy cup. Or a baby bottle. So I guess for me sippy cup.
