When my baby reached that stage, the size 4 nipple allowed milk to flow more easily, reducing feeding time and frustration.
I also found that this nipple size helps prevent air intake, which is important for minimizing colic and gas. Dr Brown’s unique vent system works best with the right nipple size, so switching to size 4 at the right time ensured my baby was comfortable and less fussy after feeds.
