Ten years of Stonyfield Farm’s YoBaby has meant 10 years of happy eating for babies -- and 10 years of happy parents as well. Now, the Londonberry, N.H.-based company has retooled YoBaby recipe slightly, with the addition of vitamin D and zinc to improve upon its already solid makeup. The yogurt remains natural and certified organic, and still contains six live active cultures. The addition of the two new items ensures that babies will receive a boost to their immunity, along with stronger bones and teeth, according to Stonyfield Farm. A six-pack of yogurt retails for a suggested $3.99. To learn more, visit www.yobabyyogurt.com.
