Thanks to the new valve, liquid only flows out of the cup when your baby is drinking. Spilling, spilling or tipping over are no longer a problem, nothing is leaking out. The beak cup is very bite resistant and makes simple drinking a breeze. Thanks to its non-slip structure and ergonomic shape, your child can hold the cup perfectly and learns to drink quickly on its own. Compatible with Philips Avent natural and Classic+ bottles (except glass bottles) and all other cups (except adult drinking cups). The cups can be combined. Drinking on your own is a big step in your child's development. We support you and try to make the transition to the beak cup from breastfeeding or the bottle easy. We work with healthcare professionals to ensure that every bottle or cup we develop supports the newly developed motor and drinking skills. Whether your baby drinks with a teat, soft or hard drinking beaks, straws or cups - they are all adapted to the child's development.
