LIFEFACTORY BABY BOTTLES

Why is glass a better choice for baby bottles?
Glass is clearly a better choice for baby bottles. Plastic bottles can leach chemicals into milk or juice (including BPA); glass does not. Plastic bottles can scratch, and scratches can harbor bacteria—glass does not. And plastic bottles typically end up in landfills when their useful life is over; glass is recyclable and reusable, and is better for the environment.

Most parents like the idea of using glass but worry about breakage.
Lifefactory offers a solution by combining a sturdy glass bottle with a custom-designed silicone sleeve to protect the glass from breaking.

The new Lifefactory baby bottles say they are “thermal shock resistant”. What does this mean?
Lifefactory is proud to bring one of the first borosilicate glass baby bottles to the world market. Borosilicate glass is pharmaceutical-grade glass that is more expensive, purer, and higher quality than other glass baby bottles that are made with soda lime. Thermal shock resistant means the glass is stronger and can withstand extreme temperature changes (from boiling to freezing) without breaking. Soda lime bottles do not have this quality. For mothers who pump and store breast milk, our bottles can go from freezer to refrigerator to hot water for feeding all in one step.

What safety certifications do Lifefactory baby bottles have?
Lifefactory are very concerned about infant safety. They have voluntarily had  their bottles tested for safety and integrity by an independent third party lab, Bureau Veritas. The bottles are in compliance with the requirements of CPSIA 2008 and 16 CFR 1500 in the United States. The bottles are EN 14350 compliant in Europe.

Why are Lifefactory baby bottles more expensive than some other glass baby bottles on the market?
It's true that Lifefactory baby bottles are somewhat more expensive than some products, but we believe the combination of safety, quality, and design makes them an excellent value.
Consider the materials: Borosilicate glass costs more but makes our baby bottles stronger and thermal shock resistant. The silicone sleeve (the hallmark of the bottles, which gives them their distinctive look, improves their "gripability," and helps prevent breakage) is much more expensive to manufacture than plastic—particularly the thick, high-grade silicone that Lifefactory does employ. Additionally, they use top-quality, FDA-approved plastic for our caps and rings, and their French nipples are medical grade silicone; both of these factors affect product pricing. A final contributor to the price of Lifefactory bottles is our commitment to rigorous product testing, which ensures safety, durability, and minimal environmental impact.

How do I wash/sterilize the bottle and its parts?
Boil or run the bottle through the dishwasher initially to sterilize. All parts are dishwasher-safe, or they can be hand-washed. The bottle and sleeve may be boiled together. You don’t need to remove the sleeve to wash the bottle, but if you wish to remove the sleeve, it comes off best in warm, soapy water. Teats should be washed on the top rack of the dishwasher only.

Do Lifefactory bottles have a venting system?
Yes, the bottles have a traditional venting system, in which ridges are located on the flange of the nipple. Tightening the ring too much will prevent ventilation and may cause nipple collapse.

What kind of Teat/Nipple is on Lifefactory bottles?
The nipples are made of silicone produced in France, where our manufacturer is that country's leading supplier of nipples. The nipples that come with our 4 oz. bottles are Stage 1 (0-3 months), and those that come with our 9 oz. bottles are Stage 2 (3-6 months).

Does Lifefactory carry other Stage nipples?
Yes. All of our nipples—Stage 1 (0-3 months), Stage 2 (3-6 months), Stage 3 (6+ months), and the Y-cut nipple—are available seperatley.

Will other nipples fit this bottle?
Yes, any standard size nipple will fit on the bottles. Wide neck nipples will not fit.

Your nipples are not marked according to Stage. How do I tell them apart?
The difference between the various nipples is flow rate, which is determined by the size of the opening. As it is difficult to distinguish the hole size on a nipple by simply looking at it, we recommend washing the nipples separately according to Stage, or not opening new nipple packages until the nipple Stage that it contains is appropriate for use. Our nipples are not labeled according to Stage for manufacturer-related reasons.

Does Lifefactory sell replacement parts?
