“Foogo, by Thermos, is a great choice for sippy cups,” says Mommy MD Guide Rallie McAllister, MD, MPH, a mom of three sons, a family physician, and the coauthor of The Mommy MD Guide to the Toddler Years, in Lexington, KY. “The cups are designed to keep beverages at the right temperature longer to prevent bacteria from multiplying. The cups come in metal or plastic, and both types have soft plastic spouts. The metal cups are designed to keep beverages cold for up to six hours. All Foogo cups are BPA free and can be put in the dishwasher.”
A seven-ounce metal cup with double-wall vacuum insulation costs $14.99, and an eight-ounce plastic cup with removable handles costs $7.99 at ShopThermos.com. You can also find the cups at Target, Walmart, Walgreens, and Amazon.com.
