Help your baby transition from bottle to sippy cup with The First Years Soft Spout Sippy Cup. The silicone spout was designed to help make the transition from bottle to cup smoother for your child. We worked with a Pediatric Feeding Specialist to be sure that both the spout size and shape help to promote proper oral development. The sippy cup also helps to prevent spills so that drinks stay inside the cup and of your little traveler and it is dishwasher safe. The sippy cup lid has a drop guard bumper that helps prevent breakage.
