Overview
The YOHKOH Natural Glass Baby Bottle is designed around a Level 2 Medium Flow nipple, which positions it specifically for infants who have progressed beyond the newborn slow-flow stage, typically from around 3 to 6 months onward. The medium flow rate is an important distinction: using a nipple that flows too fast for a young baby can cause overfeeding or choking, so the fact that this bottle explicitly specifies its flow level is a useful transparency for parents.
The glass construction is the other central feature. Glass bottles do not absorb odors or stains, can be seen through clearly to track remaining volume, and are fully compatible with sterilization methods that would degrade plastic over time. Glass naturally contains no BPA, phthalates, or other plasticizers, which is the primary reason parents choose it over plastic even at a higher price.
At $36.99 the YOHKOH sits above entry-level glass options. The 1,000 ratings at 4.6 stars are the strongest endorsement in this review: a four-digit review count with a high average suggests this is not a niche product with a narrow fan base but a bottle that works reliably across a broad range of feeding situations. The title references a natural nipple shape, which typically means a wider base designed to encourage a deep latch similar to breastfeeding.
Pros
- 4.6 stars from 1,000 ratings is strong evidence of broad, consistent owner satisfaction
- Level 2 Medium Flow nipple is clearly specified, helping parents choose the right stage
- Glass construction is BPA-free by nature and resists staining and odor over time
- Natural nipple shape is designed to support breast-to-bottle transitions
Cons
- At $36.99 per bottle, the cost is high compared to plastic alternatives and some other glass options
- Single medium-flow configuration means parents need a separate bottle or nipple for the newborn stage
- Glass adds weight that increases as the bottle fills, which some infants and parents find harder to manage
- Sparse spec data beyond what the title states, so details like capacity require confirmation from the listing
Performance notes
Based on the design and owner feedback patterns for glass bottles in this category, the YOHKOH typically works with standard steam sterilizers and dishwashers. Medium-flow nipples are generally made of silicone and should be inspected regularly for thinning or tears, with replacement every 2 to 3 months recommended by most pediatric guidance. The natural nipple shape with a wider base means proper assembly of the collar is important to avoid leaks, as the nipple must seat fully before the collar is tightened.
What buyers say
A 4.6-star average from 1,000 ratings is one of the more reassuring data points a parent can find when researching a bottle. Owners in this category commonly highlight that their babies accepted the nipple well and that the glass body cleaned up easily without the odor retention they experienced with plastic. The price is the most common hesitation noted, but buyers who make the purchase tend to report it was worth the investment.

Frequently asked questions
What age is the Level 2 Medium Flow nipple appropriate for?
Level 2 or medium-flow nipples are typically recommended for babies around 3 to 6 months old, though development varies and some babies move to medium flow later. Signs a baby is ready for medium flow include increased fussiness or prolonged feeding times with a slow-flow nipple. When in doubt, consulting a pediatrician is the safest approach.
Can I buy a Level 1 slow-flow nipple to use with this YOHKOH bottle?
Many glass bottles in this category accept nipple replacements in different flow stages using the same collar, but compatibility depends on whether YOHKOH offers additional nipple stages or whether the collar uses a standard size shared with other brands. Checking the YOHKOH product listing for available accessories is the recommended first step.
