Stonyfield Organic YoBaby Plain Whole Milk Yogurt: 0g added sugar per 1 cup (113g). Sugar Tier B.
Short answer: Stonyfield Stonyfield Organic YoBaby Plain Whole Milk Yogurt contains 0g of added sugar per 1 cup (113g) — about 0% of a child’s daily 25 g American Heart Association added-sugar limit. Tier B in our Sugar Tier System.
Stonyfield's lineup splits hard. The plain Organic YoBaby (Tier B, 0g added sugar, whole-milk, documented probiotic strains) is the most-recommended AAP-aligned first yogurt for babies 6+ months. The flavored Organic Kids line is a different story: Strawberry Banana 4.5g (Tier D), Blueberry 4.5g (Tier D), and the Organic Kids Smoothie pouches at 4–6g added sugar (Tier D–E). Per the 2020–2025 US Dietary Guidelines, the flavored variants are not appropriate for kids under 2 (recommended zero added sugar). The plain YoBaby is the buy; the flavored Kids line is the skip.
