Natural Response Glass Baby Bottle, 120ml
7.9/10 overall£11.99
A bottle with a responsive teat designed to require active sucking, similar to breastfeeding, so baby controls the flow.
The verdict
Philips Avent's Natural Response bottle has a teat that requires active sucking, like breastfeeding, so your baby controls the flow rather than milk flowing passively, priced at £11.99. It's aimed squarely at combination feeding and helping reduce overfeeding - a solid mid-range pick, though some babies used to a faster passive flow need time to adjust.
Philips Avent's Natural Response teat is designed around a specific idea: rather than milk flowing passively when the bottle is tilted, the teat requires the baby to actively suck to draw milk, mimicking the effort involved in breastfeeding more closely than a passive-flow teat. The stated goal is to help babies move between breast and bottle more easily, and to reduce overfeeding by keeping the baby, not gravity, in control of pacing.
Against NUK's First Choice+, the Natural Response system is the more research-marketed option specifically targeting combination feeding, at a moderate step up in price. Its wide, breast-shaped teat is also one of the more commonly well-accepted shapes for babies switching between breast and bottle.

Frequently asked questions
How does the Natural Response teat work?+
Rather than milk flowing when the bottle is tilted, the teat requires the baby to actively suck to draw milk out, mimicking the effort of breastfeeding and aiming to keep the baby, not gravity, in control of pacing - which the brand markets as a way to help reduce overfeeding.
Is this bottle good for combination feeding?+
Yes - it's specifically marketed at helping babies move between breast and bottle more easily, and its wide, breast-shaped teat is one of the more commonly well-accepted shapes for babies who are combination feeding between the two.
Will my baby take to the Natural Response teat straight away?+
Most babies switching between breast and bottle accept the wide, breast-shaped teat well, but some babies used to a faster passive flow from another bottle take time adjusting to the active-sucking design before they settle into it comfortably.
How does it compare to NUK First Choice+ on price and anti-colic performance?+
It's a moderate step up in price versus NUK's First Choice+, and its anti-colic valve is solid but not as thorough as Dr Brown's internal vent system, so it sits in the middle of the category on both cost and colic performance.
