Dr. Brown's Natural Flow Anti-Colic Options+ Breede Hals Sippy Fles Startersset

The spout is firm enough that my 7-month-old can gnaw on it without collapsing, yet the anti-colic vent really does cut down on the gassy fussing after feeds. We've used it as a bottle and now as a sippy, and that one-kit-two-stages idea has honestly saved us from buying a separate cup.

The handles are chunky enough for my little one to grip on her own, and swapping the nipple for the sippy spout took seconds. It's been two weeks now and the anti-colic vents still haven't leaked a drop, which makes cleanup way less stressful.

My little one took to the soft sippy spout right away, and I love that we can use the same bottles with the nipple attachment for nighttime feeds. The wide neck makes them a breeze to clean, and we haven't had a single leak since switching.
