Finding good yogurts for the boys is sometimes a hassle, specially because they like the fruity ones. They love to use it in their smoothies and as a snack. I like it since one serving has 30% of protein in this case, and protein is good specially after a soccer practice of two hours!
The downside is the sugar, this specific one has 17g of sugars, which is a lot if your kids are between 4 and 8 and trying to stay within the sugar-added guideline of 35 g of sugar per day! so eat moderately.
I usually split it a one 6 oz in two and give to each of my boys. This reduces the sugar a little bit. I also sometimes buy plain yogurt and add fresh fruit to it.
