The spout is rounded, semi-soft, and highly durable. It mimics the early approach of a straw, teaching your toddler to form their mouth into an "O" shape without chewing through the material.Patented Dual-Use Valve: * With Valve: It is 100% leak-proof and spill-resistant. Liquid is only released when the child applies suction.
Without Valve: The valve can be easily detached for free-flow drinking as your child's motor skills improve.
The spout is positioned off-center (closer to the edge) and features a tiny dimple on the lid for the baby's nose. This intentional design prevents them from having to tilt their head back awkwardly, promoting proper neck posture.
