Natural Glass Baby Bottle with Level 1 Slow Flow Nipple - Newborn

Our review of the YOHKOH Natural Glass Baby Bottle finds it best suited for parents who want a simple, breastfeeding-friendly glass bottle for early months. The single biggest reason to consider these bottles is the combination of borosilicate glass construction with a soft silicone nipple that attempts a natural latch and includes a pressure regulating valve to reduce air intake and colic. For caregivers who value easy cleaning and a glass option over plastic, these bottles offer clear advantages, though some buyers should watch for flow and durability issues reported by other users.

Key Features

• Borosilicate glass: The bottle body is made from high quality borosilicate glass that is clear and resists impurities for a clean feeding surface.
• Silicone slow flow nipple: The liquid food-grade silicone nipple is soft and designed to control milk speed for newborns, mimicking breastfeeding suction.
• Anti-colic valve: An intelligent pressure regulating valve at the nipple base helps separate milk and air to reduce swallowed air and potential colic.
• Size options: The set covers stages with 100ml/3.4oz, 160ml/5.4oz and 260ml/8.8oz bottles and includes slow and medium flow nipples to match age needs.
• Easy to clean: Simple construction with few parts allows high temperature water, steam or top-rack dishwasher cleaning and non-fading printed scales.
• Breastfeeding-friendly design: Natural response nipples let the baby control milk speed, aiding a breast-to-bottle transition.

Who It's For

The YOHKOH Natural Glass Baby Bottle works well for parents seeking a glass alternative to plastic, especially those who plan to combine breast and bottle feeding and want a nipple that responds to baby suction. It is also a good match for caregivers who prioritize easy sterilization and clear measurement markings.

Parents who need very rugged bottles for travel or who are highly concerned about breakage may want to consider other materials, since glass can break if dropped. Also, if your baby requires very slow or very fast flows beyond the included nipples, you may need to experiment or look for different nipple flow options.

Pros & Cons

Pros

• Real borosilicate glass provides a clean, non-porous feeding surface and clear appearance.
