DR BROWNS NARROW ULTRA PREEMIE NIPPLE WITH COLLAR 

The slowest of slower flow nipple rates available in the Dr. Brown’s Medical line

Often the first choice of medical professionals with very premature or medically fragile infants

Appropriate when the flow rate of a faster flow nipple is trialed, and the infant continues to show signs that the flow rate is too fast

This nipple has 35% less flow rate than Dr. Brown’s® Preemie Flow™ Nipple
