As long as I can get away with it flavored yogurt will be my kids dessert. They get 'dessert' at lunch and dinner everyday and love it. I try to buy whole (vs. lowfat) yogurt with live cultures and real fruit and mix it with some plain lowfat yougurt made at home (fortified with non-fat dry milk powder) so they don't get used to 'dessert' that is too sweet.
I have so many little containers of flavored yogurt at any given time that I actually considered starting a blog on flavored yogurts! Before my whole kids-don't-like-milk problem I had no idea that there were that many flavored yogurts out there. Coming across flavors like 'pink grapefruit' or 'orange ginger' have made me an avid flavored yogurt taster.
