Philips Avent Natural Response (Glass)

Recommended

The glass version of the world's most common bottle - a borosilicate glass body with the well-liked silicone nipple, let down only by a plastic screw ring at the seal.

The verdict: Minimal plastic contact

The glass Natural Response pairs a borosilicate glass body with the same soft, wide silicone nipple the plastic version is bought for. The one plastic in the milk path is the screw ring/collar that seats the nipple - Philips' own support page describes the plastic ring on the glass bottle - so it lands at minimal-contact: glass and silicone with a plastic ring at the seal. A real upgrade over the all-polypropylene Natural, and the ubiquitous glass option most parents can actually find in a store.

The glass Natural Response is the material upgrade to the single most common bottle on the shelf. It keeps the wide, breast-shaped silicone nipple parents like for combination feeding, but swaps the polypropylene body for borosilicate glass. Unlike boutique glass bottles, it's stocked everywhere with cheap, easy-to-find parts.

Pros

  • Borosilicate glass body replaces the polypropylene vessel
  • Keeps the well-liked wide silicone Natural Response nipple
  • Ubiquitous and affordable, with parts in every store
  • Philips clearly documents each part's material

Cons

  • Glass body is heavier and breakable; many daycares ban glass bottles
