Baby bottles
Glass and stainless steel bottles that keep milk away from plastic, with silicone or natural-rubber nipples.
Milk can reach valves, collars and lid parts as well as the bottle itself. We assess the complete bottle and exclude plastic wherever it touches milk. Exterior protective parts are identified separately. Choose the right nipple flow and follow the maker's cleaning, warming and replacement instructions.

Comotomo Gen 2 Silicone Baby Bottles (5 oz, Green, 2-Pack)
SILICONE
Why we recommend it: Milk touches the silicone bottle and nipple, while the plastic ring and cap stay outside the feeding path. The wide opening makes cleaning straightforward, and Gen 2's wider base is less easy to tip than the original design. This South Korean-made two-pack includes five-ounce bottles with slow-flow nipples intended for newborns. It is a silicone feeding option, not a completely plastic-free product.
Materials: silicone bottles and nipples · external plastic rings and caps · silicone-ink markings

Chicco Duo Glass-Lined Hybrid Baby Bottles (9 oz, 2-Pack)

Why we recommend it: A thin glass lining gives milk a glass contact surface while a plastic outer shell keeps these bottles light. Chicco's silicone nipple seals the glass-lined bottle during feeding. This is a hybrid construction, not solid glass. The bottles are made in the USA and the nipples in Italy. Use only compatible Chicco Duo nipples.
