Why Dr. Brown’s Level 4 Nipple Is Necessary
I found Dr. Brown’s Level 4 Nipple necessary when my baby started needing a faster flow to stay comfortable during feeding.

My baby also seemed more satisfied with the faster flow because it matched their stronger sucking ability. I noticed less fatigue during feeds, and my baby was able to finish bottles without getting overly tired or upset. That made feeding time feel calmer and more successful.
For me, the biggest reason it felt necessary was that it supported my baby’s changing needs. What worked at an earlier stage was no longer enough, and the Level 4 nipple gave us the right balance of comfort, speed, and consistency.
