Philips Avent Natural Response Baby Bottle SCY903/66

Baby Bottle – Philips Avent Natural Response Bottle SCY903/66

The Baby Bottle from Philips Avent (Natural Response series) is designed to mimic the natural rhythm of breastfeeding, allowing babies to drink, swallow, and breathe comfortably—just like they do at the breast. With its unique Natural Response nipple, milk flows only when the baby actively sucks, preventing spills and offering a more natural feeding experience.

Nipple releases milk when baby actively drinks

The Natural Response Nipple works with your baby’s natural feeding rhythm, making it easy to combine breast feeding and bottle feeding. The nipple has a unique opening which only releases milk when the baby actively drinks. So when they pause to swallow and breathe, the milk pauses too.

Natural latch on with breast-shaped nipple

The wide, soft and flexible nipple is designed to mimic the shape and feel of a breast, helping baby to latch on and feed comfortably.

Finding the right nipple is important

We all learn at our own pace. Suckling is a skill and some babies develop it quicker than others. That’s why some babies might initially benefit from our “First Flow” nipple (Nipple 0) before progressing to the Natural Response nipples. Switch to “First Flow” nipple when your baby takes longer than 20 minutes to drink 50 ml/1.7 oz using the Natural Response nipples. Try a Natural Response nipple with a higher flow rate if your baby is playing with the nipple instead of drinking or seems frustrated. If feeding difficulties persist, consult a healthcare professional.

Designed to reduce colic and discomfort

Anti-colic valve is designed to keep air away from baby’s tummy during feeding, to help reduce colic and discomfort.

No-drip nipple design prevents spills and lost milk

The nipple opening is designed to release milk only when the baby is feeding. So you can confidently avoid milk loss whether at home or on the go.

Choose the right nipple flow for your baby

Every baby feeds differently, and develops at their own pace. We’ve designed a range of flow rates so you can find the perfect one for your baby and personalize your bottle. All of the Natural Response Nipples are made of soft silicone.

Same products, new navigation

We have moved to a pace-based flow navigation system. Start with the nipple that comes with the bottle. Try a lower flow if milk is leaking from baby’s mouth or baby is gulping. Try a higher flow if baby is playing with the nipple instead of drinking or seems frustrated. As we make this update, you may receive either style of pack. ​

Simple to use, easy to clean and quick to assemble

Wide bottle neck makes filling and cleaning easy. Only a few parts for quick and simple assembly.

Be patient as baby adjusts

Our new Natural Response Baby Bottles are different from free-flow baby bottles. Just like breastfeeding, it could take a few tries to get it right. That’s perfectly natural.

The bottle features a wide, breast-shaped nipple that promotes an easy and secure latch, helping babies transition smoothly between breast and bottle. Its anti-colic valve is built to reduce discomfort by venting air away from the baby’s tummy, supporting calmer, happier feeding sessions.

Crafted from high-quality, BPA-free materials, the Philips Avent Natural Response Bottle ensures safe and hygienic feeding. Its ergonomic shape makes it easy for parents and babies to hold, and the wide opening simplifies cleaning and filling.

Ideal for both newborns and growing infants, the SCY903/66 model delivers comfort, natural flow, and Philips Avent’s trusted feeding performance—perfect for daily use at home or on the go.
