It’s hard to imagine where we would be without plastics, but the Sigg Kids Bottles makes a good argument for an alternative beverage holder for your babe. Cutely patterned and constructed of lightweight, seamless aluminum, these bottles are tested for 0.0% leaching, so you don’t need to worry about chemicals from plastic getting into your child's digestive system. The bottle features a non-corrosive lining, solvent-free paint on the exterior, and a leak-proof screw top that kids can open themselves.
