Drawing from the genius of apple-sauce packets, yogurt tubes are a relatively new offering. Kids simply tear off the top and squeeze the nutritious calories into their mouths. That is, of course, if you've been choosy and found the nutritious form of the popular product.
Unfortunately, many yogurt tube offerings contain added sugars and lots of fat. The yogurt tubes you're after will have a short list of ingredients that are natural and organic. Once you've determined which brand produces the healthy stuff, grab a variety of flavors and let those little students have at 'em. You'll know they're full when you find the empty tubes lying on the floor.
