Overview
A 4 ounce glass baby bottle from Lifefactory with a stage 1, slow-flow nipple and a protective silicone sleeve, sized for newborn feeding.
Lifefactory bottles are built around a glass core wrapped in a silicone sleeve, a combination meant to add drop protection without switching to an all-plastic bottle. The stage 1 nipple pairs with the 4 ounce size typical for the first weeks of bottle feeding.
- 4 ounce glass bottle
- Stage 1 slow-flow nipple
- Protective silicone sleeve
- 6.56 ounce item weight
Who it's for
Fits parents who prefer glass over plastic for feeding and are starting bottle feeding with a newborn. Less useful once a baby moves past the slow-flow stage, since the nipple will need to be sized up.
Pros and cons
- Glass construction avoids plastic contact with milk
- Silicone sleeve adds drop protection and grip
- Stage 1 nipple suited to newborn slow-flow feeding
- 4 ounce size will be outgrown as feeding volume increases
- Single bottle per pack, not a multi-pack
Performance notes
The stage 1 nipple is designed for slow, controlled flow suited to a newborn who is still learning to bottle feed, and the silicone sleeve wraps the glass body to cushion drops and add grip. At 4 ounces, the bottle matches typical early feeding portions rather than the larger volumes older babies need.
