NUK First Choice Glass Bottle 240ml

The NUK First Choice Glass Bottle 240ml with Silicone Teat is a wide-neck glass baby bottle for babies aged 0–6 months, designed to carry expressed breast milk or formula. It comes fitted with a Size 1 medium-flow (M) silicone teat, a flow the supplier recommends for formula feeds, so it's ready to use straight out of the box with its screw ring, teat and protective cap.

If you're combining breast and bottle feeding, or expressing and offering a bottle alongside nursing, this is where NUK's First Choice system focuses. The teat uses NUK's familiar asymmetric, orthodontic shape — a curved upper surface and flatter underside modelled on the shape of the breast during feeding — which is intended to encourage natural sucking movements. NUK describes the bottle as clinically tested to support combined breast and bottle feeding (Moral et al., BMC Pediatrics 2010, 10:6).

A glass bottle for parents who prefer natural materials

The bottle body is made from heat-resistant borosilicate glass — a good fit if you'd rather avoid plastic entirely. Glass is hard-wearing, easy to clean and resists staining or holding onto odours, and NUK notes it is BPA-free and odourless. The slightly contoured shape is easy to hold, the wide base adds stability when you set it down, and the extra-wide neck makes both filling and cleaning simpler. Every part — the teat, screw ring and cap — removes for thorough washing.

How the teat and anti-colic system work

• Orthodontic teat shape: The asymmetric design was developed with medical experts and is shaped to leave room for the tongue and jaw to move during feeding.
• NUK Anti-Colic Air System: A valve lets air into the bottle as baby feeds to balance the pressure inside, which is designed to help reduce the air baby swallows and, in turn, the risk of colic and feeding discomfort.
• Offset hole: The teat's offset hole is designed to let milk mix with saliva during feeding for a more natural feel.
• Soft zone: A softer area on the teat gently conforms to the roof of baby's mouth for a breast-like sensation.
• Collapse-resistant teat: The teat is designed to resist collapsing mid-feed, helping keep the flow smooth and uninterrupted.
• Temperature Control: The normally blue indicator turns white if the feed is too hot, giving you a quick visual cue.

Flow and stage

This bottle ships with the medium-flow (M) teat suited to formula. Within the wider First Choice range, teats are also offered in Small (S) for breast milk, water or tea and Large (L) for thicker feeds, with Size 1 teats for newborns (0–6 months) and Size 2 for older babies (6–18 months). Flow labels are a guide — your baby's feeding cues are the best signal of whether a flow suits them. The bottle also comes in 150ml, 240ml and 300ml capacities.

How to use and keep it clean

1. Before first use, place the parts in boiling water for 5 minutes, using enough water to avoid damage.
2. Always dismantle the bottle into its separate parts before boiling or steam-sterilising.
3. Clean thoroughly with a mild washing-up liquid.
4. Sterilise before every use — NUK recommends the NUK Steriliser.

Best for

The NUK First Choice Glass Bottle with Silicone Teat 240ml is a good option for parents who:

• Prefer glass over plastic and want a durable, easy-to-clean bottle body
• Are combining breast and bottle feeding and want a familiar orthodontic teat shape
• Are feeding formula and want a medium-flow teat ready to go
• Already use, or plan to use, other NUK First Choice components

It may not be the best fit if you:

• Want the lightest, most break-resistant bottle for travel and on-the-go feeds

Compatibility

The bottle is combinable with all NUK First Choice products, so teats, rings and caps can be swapped within the range as your baby grows. First Choice parts are also interchangeable with NUK's Evolution Cup range, including Learner cups and NUK soft-spout and hard-spout Active Cups.

Pandylane Pro Tip: Because First Choice components move across the Evolution Cup range, the same system can carry you from bottle to learner cup without switching brands — worth keeping in mind when you're building up your feeding kit.

Please note

For hygiene and safety, inspect teats regularly and replace them every 1–2 months, or sooner if any tears or cracks appear. The Temperature Control indicator is a helpful cue, but always check the feed temperature yourself before feeding.
