Always prepared for the unexpected with the flipple adapter on hand. Add a nipple to bottled water when this adapter turns a water bottle into a baby bottle. It's the easiest way to feed your child while on the go and to get them to drink water as they grow older. This funnel shaped adapter allows formula or supplements to be added to the small opening of bottled water then it is flipped and screwed onto the water bottle so a nipple can be added. Keep the small adapter in your nappy bag so all you need to carry are clean nipples and that is all that is left to wash at the end of the day.
