5 reasons to choose a standard nipple

"Developed in response to mothers' needs"

This is a softer nipple created prioritizing “milk feeding”, which passed strict tests on numerous

features including size of hole, softness of silicon, smooth opening of air valve, and durability. This

nipple will support your baby’s instinct of “wanting" to drink: compared to the Brain nipple that

provides challenges for babies to suckle, it lets them gulp their milk to their hearts’ content.

Compatibility of Brain and Jewel Series

All bottles, nipples, hoods, and caps of Brain Series and Jewel Series are compatible with

each other. Switching nipples day to day according to how your baby suckles is indeed

what mothers who watch their babies every day can do. Mothers may also enjoy choosing

the colors of hood and cap to match their mood that day.
