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

The Level 4 Nipple gave a better balance by allowing milk to flow at a speed that matched my baby’s needs, which made feeding calmer and more successful.
I also appreciated that using the correct nipple level helped support a more natural feeding rhythm. It felt important to choose a nipple that matched my baby’s development instead of forcing a slower option that no longer worked. For me, Dr. Brown’s Level 4 Nipple was necessary because it helped turn feeding from a struggle into a more comfortable and consistent experience.
