Overview
The yanyoyo Natural Glass Baby Bottle is designed for breastfeeding babies and comes in a practical 4-pack format. At 5.4 ounces per bottle, the capacity suits newborns through the early months, and having four bottles on hand means less frequent washing during busy days. The anti-colic design is a key selling point for a bottle positioned at breastfeeding babies, where reducing air intake and gas discomfort is a common parenting priority.
Glass is the standout material choice here. Unlike BPA-free plastic, glass does not absorb odors, does not stain, and does not degrade with repeated high-temperature sterilization. Many parents choose glass specifically because they want to avoid any long-term questions around plastics. The tradeoff is weight and fragility, and at 11 ounces per bottle (as stated in the specs), these are on the heavier side, which matters when a parent is feeding in the middle of the night.
With 241 ratings and a 4.3-star average, the yanyoyo bottle has a moderate review base. Around 50 units were purchased last month, indicating steady if not high-volume demand. The $34.99 price for a 4-pack works out to roughly $8.75 per bottle, which is a fair price for glass anti-colic bottles when compared with the market broadly.
Pros
- Glass construction resists odors, stains, and material degradation from repeated sterilization
- 4-pack format reduces how often parents need to wash bottles during the day
- Anti-colic design for breastfeeding babies addresses a common concern for nursing families
- $34.99 for four bottles represents reasonable per-bottle value for glass
Cons
- At 11 ounces each (per listed weight), these are heavier than plastic alternatives, which may be tiring during extended feeds
- Glass can break if dropped, which is a practical concern in a household with young children
- 4.3 stars from 241 reviews is decent but not the strongest confidence signal compared to bottles with thousands of ratings
- 5.4 oz capacity is suited to younger babies and will likely need to be replaced as feeding volume increases

Performance notes
Based on the product title and owner reviews, the anti-colic feature in this bottle is designed to reduce the air a baby swallows during feeding, which reviewers credit for helping babies remain calmer after meals. The breast-like nipple shape, as indicated by the 'natural' positioning in the title, is intended to mimic a breastfeeding latch and ease the transition between nursing and bottle feeding. Glass bottles are typically safe for dishwasher cleaning and steam sterilization, though the nipple components should be checked separately. Leakproofing when reassembled properly is noted positively by reviewers.
What buyers say
With 241 ratings at a 4.3-star average, the yanyoyo glass bottle has attracted a reasonably positive response. Reviewers who prefer glass for their babies tend to highlight the clean feel and odor resistance of the material. Some reviewers note the weight of the glass body as something to get used to. The brand is newer and less established than major bottle names, which is a fair consideration for parents who place weight on long-track-record brands.

Frequently asked questions
Are these glass bottles safe to boil or steam sterilize?
Glass baby bottles are generally safe for steam sterilization and boiling, and most owners of this type of bottle confirm that. The nipple components are typically made of silicone, which is also sterilizer-safe, but parents should confirm with the product's included care guide before sterilizing in appliances like a microwave steam sterilizer.
Do these bottles work with a breast pump?
Standard-neck glass bottles do not always connect directly to breast pump flanges, and compatibility depends on the pump brand and flange size. Wide-neck bottles have broader compatibility. It is best to verify the neck size against your specific pump's connector before purchasing if direct pumping into the bottle is a goal.
