Bình sữa cổ rộng chống đầy hơi Natural Flow Options+ Dr. Brown's, 5oz/150mL, Gói 2

The internal vent system actually works—my baby's gas issues cleared up within a week, and the wide neck makes pouring formula way less messy at 2 a.m.

The internal vent system actually works—my baby’s fussiness dropped noticeably within a week, and the wide neck makes pouring and cleaning way less messy than I expected.
