The bökee was created by parents to simplify bottle prep for all parents and caregivers. Bottles and sippy cups can be opened, filled, and closed with just one hand, leaving the other for baby, toddler, or multitasking. bökee is also perfect for transferring breast milk safely from bag to bottle, removing pump parts or keeping silicone pumps upright. It keeps the bottle upright to reduce the accidental knock over, and since it's made from 100% silicone, if any milk is over poured into the bökee it can be poured back into the bottle with confidence and no waste of that hard earned milk!
