Overview
A 2-pack of 4 ounce glass baby bottles from Munchkin's Bond line, each coated in silicone and built with anti-colic venting for newborn feeding.
The silicone coating over the glass body is meant to reduce breakage risk while keeping the bottle free of plastic contact with milk. Anti-colic venting is aimed at reducing the air a baby swallows during feeding, which can help with gas and spit-up.

Who it's for
Works for parents feeding a newborn who want glass bottles without a bare glass surface, and who want anti-colic venting. Two bottles per pack is enough for a basic rotation but not a full daily supply on its own.
Strengths and trade-offs
Drawn from this product's published specifications.
- Silicone-coated glass reduces breakage risk
- 4 ounce size fits newborn portions
- Only 2 bottles per pack
Performance notes
The anti-colic design routes air away from the milk path during feeding, a mechanism intended to cut down on the air a baby swallows. The silicone coating sits directly over the glass, a different approach from a separate sleeve, which keeps the bottle slimmer.
