My son was such a picky baby. We have tons of brand name bottles. I had Dr. Brown, Tommy Tipton, Playtex, Advent, etc. My child would only use these and wouldn’t take to any other bottle. It reminded him maybe if a breast because of how big it is and the nipple. I liked the latch it is made to help reduce colic. Super easy to clean as the blue tap in the bottom pulls out to make cleaning easier. Not too expensive.
