Yet another BPA-Free sippy cup option! Think Baby bottles and Think Baby sippy cups were created to address the growing concern of toxic chemicals potentially leaching from baby products. The Think Baby trainer cup bottle was designed to be free of toxic chemicals like bisphenol-A, lead, PVC and phthalates. The baby bottle features a silicone spout to ease in the transition from bottle feeding to cup feeding. The little kids were chewing on the hard plastic, so we continued with the use of soft silicone for our spout. The trainer cup features fun to hold handles and a travel cap to reduce chance of spillage during travel.
