This bottle is perfect for breastfed babies refusing a bottle.My baby is primarily breastfed and would refuse bottles when babysat. After trying a few different bottles and different hacks to get her to take one I ordered this one as the reviews both on here and on tiktok all looked promising.She accepted the bottle immediately when offering it to her. It did not make her gag, the flow was not too much for her, and you could tell it was a comfortable fit opposed to other bottles with long nipples that are stiff.I found it easy to clean, I loved that it came with a lid for storing milk as well. I never write reviews but after struggling to find the right one I was very impressed with this one!
