Dr Brown's Natural Flow Narrow-Neck Options+ Glass Bottle 120ml

The Dr Brown's Natural Flow Narrow-Neck Options+ Glass Bottle 120ml is a small-capacity glass baby bottle for feeding expressed breast milk or formula. It pairs a narrow-neck glass body with a silicone teat and Dr. Brown's internal vent system, and is part of the Options+ range — so it fits alongside other Dr. Brown's narrow-neck teats and spares as your feeding routine settles.

The 120ml size suits the smaller feeds of the early weeks, while the silicone teat delivers a consistent flow that lets baby feed at a comfortable, unhurried pace. The teat's breast-like shape is designed with the move between breast and bottle in mind, which can be reassuring if you're combination feeding.

Heat and thermal shock-resistant glass

The bottle is made from glass that Dr. Brown's describes as heat and thermal shock-resistant, so it can handle hot and cold temperatures as well as gradual temperature changes. Glass is easy to see through for checking volumes and tends not to hold onto smells over time. The bottle is BPA free and, according to Dr. Brown's, 95% recyclable.

A vented system that grows with baby

This is a vented bottle, and the internal vent system is central to how it works. It's designed to sit inside the bottle during feeds, and can be removed later as baby's feeding develops — meaning you can carry on using the same bottle rather than switching to a new one as your baby matures.

How it Works

• Internal vent system: An anti-colic vent design intended to manage air and vacuum during feeds; it works best with the vent in place and can be taken out as feeding develops.
• Consistent-flow silicone teat: The silicone teat is shaped to give a steady flow so baby can feed at their own pace.
• Options+ narrow-neck system: Part of Dr. Brown's narrow-neck range, so it works within the wider Options+ system of teats and replacement parts.

Cleaning and sterilising

Like all vented bottles, this one has a few parts to take apart and clean thoroughly after each feed. It's safe for the dishwasher (top rack only), and can be sterilised using electric or microwave sterilisers or in boiling water.

Best For

The Dr Brown's Natural Flow Narrow-Neck Options+ Glass Bottle 120ml is a great option for parents who:

• Prefer a glass bottle body over plastic
• Want a smaller capacity suited to the early weeks of feeding
• Like the idea of a vented system they can adapt as baby grows
• Are combination feeding and moving between breast and bottle

It may not be the best fit if you:

• Want a lightweight, shatter-resistant bottle for on-the-go use
• Prefer the simplest possible bottle with the fewest parts to clean
