When it comes to innovation, health, and ease of use, these bottles by Adiri are naturals. The rounded shape is designed to mimic a mother's breast and reduce nipple confusion, and the body and nipple are all one piece, with a fill-from-the-bottom construction that makes them easy to use and easy to clean. Recommended by doctors, nurses, and lactation consultants, they're also made without Bisphenol-A (BPA) for worry-free use. A giggle favorite!
