• Can be used with all Dr Brown\'s bottles. • Keeps the vent and reservoir clean. • Dishwasher safe. • Allows the bottle to work properly. • Four brushes in a pack. Dr Brown’s Options Bottles are part of a complete family of products that grows with your baby, including coloured bottles & accessories, cleaning and sterilising equipment, soothers & teethers, plus a range of trainer and transition cups. As baby becomes more developed the bottle can be used without the green vent system to work more like a conventional, teat-vented bottle. The new Dr Brown’s scalloped designed teat allows air to vent through the bottle when the green vent system is not used, ideal for when baby’s feeding is more developed or parents just want the convenience of a teat vented bottle.
