YOHKOH Natural Glass Baby Bottle with Slow Flow Nipple - Newborn

Our review of the YOHKOH Natural Glass Baby Bottle finds it best suited for parents who want a simple, breast-friendly feeding option made from glass. The standout reason to consider these bottles is the use of borosilicate glass combined with a soft liquid silicone nipple that aims to mimic breastfeeding and reduce air intake during feeds. For caregivers prioritizing easy cleaning, clear scale markings, and a natural response nipple, this pack-oriented bottle is a practical choice for early months and as the baby grows.

Key Features

• Borosilicate glass: Provides a pure, clear bottle material that resists staining and feels solid compared with typical plastic alternatives.
• Liquid silicone nipple: Soft food-grade silicone nipple closely mimics a natural breastfeeding sensation and allows babies to control milk flow.
• Pressure regulating valve: The nipple base balances internal and external pressure to separate milk and air, helping reduce colic from swallowed air.
• Stage sizing: Available in 100ml, 160ml, and 260ml sizes with slow and medium flow nipples to match 0-12 month feeding needs.
• Easy to clean: Few parts and dishwasher-safe on the top rack, plus the bottle uses non-fading ink for clear measurement scales.

Who It's For

The YOHKOH glass bottle is ideal for parents who prefer glass over plastic for purity and want a breastfeeding-friendly nipple that lets the infant control flow. It also fits families who value durability of print and easy cleaning methods, including high-temperature washing or steam sanitizing.

Those who need ultra-durable, shatterproof bottles for very active toddlers or who require a wider selection of nipple textures and flow adjustments may want to compare silicone or specialist anti-leak systems before deciding.

Pros & Cons

Pros

• Real borosilicate glass for a clear, pure bottle experience and resistance to staining.
• Soft, food-grade silicone nipple with a pressure valve to help reduce swallowed air and mimic breastfeeding.
• Simple design with clear, non-fading scale markings and easy cleaning options including top-rack dishwasher safety.
• Multiple bottle sizes and flow options to cover newborn to toddler transitions.

Cons

• Glass can break if dropped, so durability in rough use is a realistic limitation.
• Flow rate impressions vary among users, with some finding the supplied slow flow faster than expected for certain babies.
