Parents who are willing to splurge on a durable, eco-friendly glass bottle will want to consider the Lifefactory Glass Bottle (Est. $57 for four 9 oz. bottles) . It comes with a medical-grade silicone sleeve that makes it comfier to hold and helps cushion falls, and the tough, borosilicate glass can withstand temperature extremes better than other types of glass. Lifefactory bottles can also become sippy cups or snack containers with the addition of new caps. However, experts say they might not be the best pick for babies prone to gas or latch problems because the nipples are fairly narrow and there's no venting system. The bottles are also heavier than their plastic counterparts.
Evenflo's Classic Glass Bottle (*Est. $13 for three 8 oz. bottles) is an economical option for parents who want to steer clear of plastic but keep their wallet from feeling the pain. Reviewers say the bottle's old-fashioned, simple design makes it easy to assemble and wash; just be aware that the narrow neck might make some bottle brushes a tight fit. The vented, pressure-sensitive nipple aims to cut down on feeding issues, but reviewers say it's on the small side. Parents say the bottle is compatible with a few other brands of nipples. Some warn that this isn't the most durable glass bottle you can buy, saying it might not stand up to temperature extremes or breakage as well as Lifefactory bottles, for example.
Dr. Brown's Glass Bottle (*Est. $20 for three 8 oz. bottles) splits the difference between Lifefactory and Evenflo on price. Its claim to fame is a comprehensive anti-colic venting system that extends a straw deep into the bottle. Many parents swear by Dr. Brown's bottles for cutting down on excess air intake and the fussiness that comes with it, but experts note one downside: There are lots of small parts to clean and assemble. Measurements are also difficult to make out, reviewers say.
