The baby cup is designed for drinking from any angle, perfect for babies starting with straws from 6 months. It features a clever two-piece valve that stops leaks, preventing spills while transitioning from a bottle to a straw. The soft silicone straw is gentle on gums but tough enough for tiny teeth. Clear measurement markers let you track how much your baby has drunk, and the cover flips up and down between sips to keep the straw clean. With easy-to-hold handles and a cleaning brush included, this cup is dishwasher and sterilizer safe and BPA-free.
