Our baby and toddler sippy cup is made of 100% LFGB food-grade silicone. As your baby begins the transition from bottles to cups, our silicone sippy cup helps develop motor skills and independent eating habits. • SHATTERPROOF: The easy-grip, non-slip material makes the cup perfect for babies aged 6 months and up and children aged 1 to 3 years. Double handles make it easy for babies and toddlers to hold. The transition cup can also be used without lid as an open children's cup or as a snack container for children.
