With its Natural Flow bottles, Dr. Brown is one of the number one mother and baby brands in the United States. The Natural Smooth Baby Bottle is currently the only bottle with a ventilation catheter system, ranking first in sales in the United States, which can effectively reduce gas pain, relieve flatulence, hiccups, etc., which can be said to be the brand foundation of Dr. Brown, and has also won the American Medical Design Gold Award.

Dr. Brown's three-compartment milk powder carton is also extremely popular in the United States, ranking among the top three on Amazon's sales list in the United States. The three-grid milk powder box design has its own uniqueness, there are grooves on both sides, easy to take, the upper lid mouth is slightly convex, forming a small funnel, the powder outlet can be put into the mouth of the standard caliber bottle, and the powder will not be sprinkled outside the bottle to cause waste, but the outlet is smaller, and it is more difficult to pour the powder clean.

The price of the three-grid milk powder box is 35 yuan, the sealing is good, the snap-on upper lid plug is tight enough, and when the lid is closed, the sound of "click" is heard to indicate that the lid is tight, and it is not easy to leak powder in the bag, but the rotation of the upper lid is more astringent, and after using up a grid of milk powder, it is necessary to re-align the powder outlet to another inner grid, which is slightly troublesome to use. In addition, Dr. Brown's milk powder carton should not be microwaved, high-temperature sterilized, and can be washed with a mild detergent or on the top layer of the dishwasher.
