Lifefactory 9oz Glass Sippy Bottle

Prior to modern manufacturing technologies, producing glass was quite labor-intensive, so it was very expensive, and it was unusual to use a lot of glass in your home. It was notable enough that the will of Governor Fauquier of Virginia, who died in 1768, listed his entire glass collection, with itemized beer glasses, champagne glasses, water glasses, wine glasses, syllabub glasses, jelly glasses, glass salvers, decanters, and cruets. We're willing to bet that something got broken on the way out of his house.

These days, glass is often bypassed in favor of less-fragile plastic, but with recent fears about chemicals, glass is coming back. The Lifefactory Sippy Top 9 Oz Bottles combat the fragility of glass with cute, grippy silicone sleeves that help them survive being dropped, which means that they're perfect for toddlers. If you've been using Lifefactory bottles, the sleeve will also help ease the transition, since your child is already used to drinking out of something that looks and feels the same.

These sippy cups have leak-resistant tops with steady flow control, and you can control the silicone valve flow rate by tightening or loosening the cap. As with all Lifefactory products, the Sippy Top 9 Oz Bottles contain no BPA, phthalates, PVC, or latex – so there's nothing to worry about while teaching your little guy to drink like a big kid.
