I don't know if I've ever mentioned this before, but we aren't big bottled juice drinkers. We always make our juices fresh when we do drink them. I really don't see any benefits to bottled juice especially when he's still just a toddler. Since he's never really had a whole lot, it's easy for him to know that when he's thirsty he has water to drink. He occasionally gets green juice when I make it and let him have as much as he wants and the only other thing is herbal tea with a little honey (but that's mostly just when he's sick).
The second reason we make all our own juice, is because it's just plain fun. Everett gets such a kick out of watching solid things turn into something he can drink. I always let him help when he wants to, he usually does and is always a big helper. He's been really good at helping me clean up afterwards and everything. It's such a fun hands on thing for him to do. And it makes it that much more of a treat to him.
Footnote: The first set of photos is from only a couple months ago. He looks so much smaller than normal to me for some reason! It's amazing how fast he grows!
