I ended up with juice boxes that were leftover from a Judo tournament, so I let each boy have one at dinner last night. M (who has developed a wonderful compulsion to read any print he sees), read the ingredients to himself. We knew this because all of the sudden he exclaimed excitedly:
"This has apple, grape, and BEER!"
These were 100% juice juice boxes, so I was pretty sure he was wrong. I think he was a bit disappointed when we informed him that it only contained apple, grape, and pear juices.
