As with most teats, the original Natural teat drips milk freely if the bottle is held upside down. On the other hand, the Natural Response teat will not leak and only flows when your baby actively drinks. The teat behaves as a breast would, making it easier for your newborn to continue their natural drinking pattern, and they can pause when needed. 

It may take a few attempts for your newborn to become familiar with the Natural Response teat. So do not get discouraged should your little one refuse the new teat after a few tries. It may take up to 2 to 3 attempts until your little one finds the teat to their liking.
