Overview
A vented nipple is the working part of this anti-colic bottle, paired with an extra slow flow rate for the newest feeders. The title describes a glass bottle meant for breastfed infants and a natural feeding style.
Extra slow flow and a vented nipple are the reasons to look at it for a newborn, and the specs say it is dishwasher safe and microwaveable. Missing details include the nipple material, whether a cap or spare nipples come with it, and the bottle dimensions.
Who it's for
Parents starting out with a breastfed newborn and looking for a vented, slow-flow bottle. Babies who drink fast need a quicker flow, and anyone after a multi-bottle set will find only a single bottle here.
Pros and cons
- Extra slow flow for newborns
- Vented anti-colic nipple
- Microwaveable per listing
- Single bottle only
- Nipple material not listed
- Slow flow only, no faster nipple
Performance notes
Flow speed is set by the nipple, and an extra slow rate suits newborns who feed gently. The vent is the basis of the anti-colic claim, since it is meant to limit air taken in during a feed. Glass holds heat, so test the temperature of warmed milk before feeding.
