How do the Anti-Colic Ring and Anti-Colic Bottle work?
The Anti-Colic Ring can be used with any Nurtria wide neck bottle. The Anti-Colic Bottle is a regular wide neck bottle that comes with the ring. Place the ring on the neck of the bottle. Screw on the screw ring with nipple. When feeding, you will notice bubles going into the bottle. This indicates that air is replacing the milk coming out of the bottle. This prevents a vacuum from occuring which leads to baby sucking in air, which may cause colic.
