YOHKOH Natural Glass Baby Bottle 8.8oz Pack of 4 - Clear Green

In this review of the YOHKOH Natural Glass Baby Bottle pack, the bottom line is simple: parents who want a pure glass feeding option with a breastfeeding-like flow will appreciate these bottles. The set reviewed is the clear 8.8oz (260ml) size sold as a pack of four with green accents, and the biggest reason to buy is the borosilicate glass construction paired with a liquid silicone natural response nipple that helps separate milk and air for gentler feeding. It reads and cleans like glass and is intended to cover the 6-12 month feeding stage with a medium flow nipple.

Key Features

• Borosilicate glass body: The bottles are made of high quality borosilicate glass that is clear and free of impurities, which makes them easy to inspect and clean.
• Natural response nipple: The liquid silicone nipple adjusts flow to the babys suction, giving a feeding feel closer to breastfeeding and helping control milk speed.
• Pressure regulating valve: A valve at the base of the nipple balances internal and external pressure to separate milk from air and reduce colic risk.
• Age-graded sizing: The 260ml 8.8oz bottles use an M nipple suitable for roughly 6-12 months, matching the packs intended feeding stage.
• Simple construction: Only a few parts make assembly and cleaning straightforward, and the bottles tolerate high temperature water or steam cleaning.
• Durable markings: Bottle pattern and measurement scales use non-fading ink for clear, long-lasting measurement visibility.

Who It's For

These 8.8oz glass bottles are best for parents of older infants around 6-12 months who need a larger bottle with a medium flow nipple and prefer the hygiene and clarity of borosilicate glass. They are a good fit for caregivers who prioritize a bottle that mimics breastfeeding flow and who will benefit from a valve that aims to reduce swallowed air.

Parents who need a newborn option or a slower flow should look to the smaller 100ml or 160ml sizes with S nipples, or choose a bottle explicitly noted for very slow flow. Families who need a shatterproof solution or who are highly concerned about breakage in a busy household should consider a different material.

Pros & Cons

Pros

• Real borosilicate glass gives a pure, clear bottle that is easy to clean and inspect.

• Pack of four 8.8oz bottles provides good value for parents using multiple bottles per day.

Cons

• Glass can break if dropped, and some customers report durability concerns and occasional leakage when not assembled carefully.
• Flow rate may be too fast for some newborns despite the M nipple being intended for older infants.
