YOHKOH Natural Glass Baby Bottle with Natural Response Nipple - Clear

Our review of the YOHKOH Natural Glass Baby Bottle finds it best suited for parents who want a clear, simple glass bottle that mimics breastfeeding and is easy to sanitize. The single biggest reason to consider these bottles is the combination of borosilicate glass construction with a liquid silicone "natural response" nipple that aims to regulate flow based on baby suction and reduce air ingestion. They are available in three capacities to match infant stages and come in a wide neck design that makes filling and cleaning straightforward.

Key Features

• Borosilicate glass: The bottle body is made from high quality borosilicate glass that is clear and resists impurities for easier inspection and cleaning.
• Natural response nipple: The liquid silicone nipple adjusts flow to the baby's suction, offering a more breastlike feeding pace for infants used to nursing.
• Pressure regulating valve: An intelligent valve at the nipple base balances internal and external pressure to separate milk and air and help reduce colic from swallowed air.
• Multiple sizes: Comes in 100ml, 160ml and 260ml sizes with S and M nipple options to match 0-3, 3-6 and 6-12 month feeding needs.
• Wide neck and simple parts: The wide neck and minimal components make assembly and a variety of cleaning methods, including steam or hot water, easy to perform.
• Durable markings: Bottle patterns and measurement scales use non-fading ink for long-term readability.

Who It's For

The YOHKOH glass bottles suit caregivers who prefer glass over plastic for hygiene and clarity, and who value a nipple that attempts to mimic breastfeeding with a variable flow. They are a sensible choice for families who will regularly sterilize bottles since borosilicate glass tolerates high temperatures.

Parents seeking ultra-durable, shatterproof bottles or those who need extremely slow newborn-only flow may want to look elsewhere, as some customers reported concerns about durability and that the flow can be too fast for the smallest infants without additional flow control.

Pros & Cons

Our Verdict

The YOHKOH Natural Glass Baby Bottle is a good value for caregivers who want a glass bottle with a breastfeeding-like silicone nipple and an anti-colic valve. It offers clear construction, easy cleaning, and size progression to grow with a baby, but buyers should handle glass carefully and consider additional slow-flow nipples for very young newborns. Overall, it is a practical choice for parents prioritizing glass and simple, hygienic design.

Frequently Asked Questions

Which nipple suits a newborn?
The 100ml and 160ml sizes use an S nipple intended for 0-3 months and 3-6 months respectively; some newborns may still prefer an even slower flow.

Do the bottles prevent colic?
The nipple includes a pressure regulating valve to separate milk and air which can reduce swallowed air, but individual results may vary.
