Overview
Sold as a 4 pack, this yanyoyo bottle holds 5.4 ounces of glass construction designed for breastfed babies and marketed with an anti-colic design. Each bottle weighs about 11 ounces.
Glass construction is often chosen over plastic to avoid leaching concerns, though it adds weight and breakage risk compared to plastic bottles. The anti-colic claim points to the nipple or vent design reducing air intake during feeding.
- 5.4 ounce capacity
- Natural glass construction
- Anti-colic design
- Pack of 4
Who it's for
Parents who prefer glass bottles over plastic for breastfed babies and want a multi bottle set rather than buying one at a time. Less practical for parents who prioritize drop resistant bottles for an active older baby.
Strengths and trade-offs
Drawn from this product's published specifications.
- Glass construction avoids plastic leaching concerns
- Sold as a 4 bottle pack
- Anti-colic design aims to reduce air intake
- Glass is heavier and can break if dropped
- 5.4 ounces is a small capacity for an older baby
Performance notes
The anti-colic design is intended to limit air bubbles during feeding, which can otherwise contribute to gas and fussiness. Glass does not retain odor or stains the way some plastics can over repeated use.
