Featuring an anti-colic valve to reduce discomfort and a no-drip design for mess-free feeding, these 4oz bottles are heat and thermal shock resistant, easy to clean, and designed for seamless breast-to-bottle transitions. Trusted by pediatricians and parents alike, this 4-pack supports healthier, happier feeding moments. ## Description The Philips Avent Natural glass baby bottle is designed for first-time and experienced parents who prefer premium borosilicate glass while combining breast and bottle feeding. The Natural Response nipple releases milk only when baby actively drinks, letting baby control the pace like breastfeeding; when baby pauses to swallow and breathe, no milk flows. Its wide, soft and flexible breast-shaped nipple supports a comfortable latch, while the no-drip design helps prevent spills and lost milk. An integrated anti-colic valve sends air away from baby's tummy to reduce colic and discomfort. Premium borosilicate glass is BPA-free, heat and thermal shock resistant, so the bottle can be stored in the fridge, warmed, washed and sterilized with confidence. The ergonomic shape is comfortable to hold, and a few parts plus a wide bottleneck simplify filling, assembly and cleaning. This 4oz bottle includes a slow flow nipple (Flow 2) and is designed for use with Philips Avent Natural Response bottle nipples. Five nipple flow rates are available; age is a guide, while baby's drinking approach and feeding cues help determine when to move up or down in flow. It is the #1 Pediatrician recommended natural baby bottle¹, giving parents reassuring material durability without giving up a natural feeding rhythm. ¹ IQVIA Health ProVoice Survey 2025, USA Review: Love these glass bottles! No colic and easy to clean - I switched to these Philips Avent Natural Glass bottles and I love them! The glass is high quality and feels so much safer than plastic, no worries about chemicals. They are easy to clean and don't keep the milk smell. My baby latched easily and the medium flow is perfect, no more colic or extra gas. The anti-colic valve really works. They also fit perfectly in my GROWNSY bottle washer. Worth the price for peace of mind. Will definitely buy more! Review: ⭐⭐⭐⭐⭐ High-quality glass bottles, perfect for newborns - I really love the Philips Avent Natural Glass Baby Bottles. The glass feels premium, sturdy, and much more durable than I expected. I appreciate that the material is easy to clean, doesn’t retain odors, and feels like a safe option for my baby. One thing I especially appreciate is the temperature retention. The glass helps maintain the milk’s temperature better than some plastic bottles, keeping it warm for a longer period while feeding. It is also easier to check the temperature because the bottle material responds well to temperature changes. The slow-flow nipple works great for newborns because it allows a more controlled feeding pace and helps reduce overwhelming milk flow. The Natural Response design feels closer to breastfeeding, making it easier for babies who switch between breast and bottle. The 4 oz size is perfect for the early months, especially for smaller feedings. The bottle is comfortable to hold, easy to assemble, and simple to sterilize. The quality of the nipple and bottle has held up well with daily use. The only thing to consider is that glass bottles are heavier than plastic ones, so they require a little more care when handling. Overall, this is an excellent bottle with great quality, a thoughtful design, and a size that is ideal for newborns. I would definitely recommend it. ## Features - Natural Feeding Rhythm: Baby controls the pace of milk flow like breastfeeding, supporting a familiar rhythm; #1 Pediatrician recommended natural baby bottle¹ - Premium Glass Material: Premium borosilicate glass is BPA-free, heat and thermal shock resistant; safe for fridge storage, warming, washing and sterilizing - Breast-Shaped Nipple: Soft, wide nipple mimics the shape and feel of a breast, supporting a comfortable latch and easier breast and bottle feeding - No-Drip Flow 2: No-drip nipple helps prevent spills and lost milk at home or on the go; each bottle includes a slow flow nipple (Flow 2) - Anti-Colic Valve: Integrated valve keeps air away from baby's tummy during feeding to reduce colic and discomfort for a more reassuring feed - The set includes: 4x 4oz Natural glass baby bottles with slow flow nipples (Flow 2) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B098YHHV3Q | | Age Range Description | Baby | | Best Sellers Rank | #46 in Baby ( See Top 100 in Baby ) #2 in Baby Bottles | | Bottle Nipple Type | Vented | | Bottle Type | Vented Bottle | | Brand | Philips Avent | | Capacity | 4 fluid ounces | | Color | Glass | | Customer Reviews | 4.6 out of 5 stars 10,776 Reviews | | Global Trade Identification Number | 00075020093042 | | Included Components | 4 4oz Natural Glass bottles with Flow 2 Natural Response nipples | | Item Weight | 4 ounces | | Liquid Flow Speed | medium | | Manufacturer | Philips Avent | | Material Type Free | BPA Free | | Number of Items | 4 | | UPC | 075020093042 | | Unit Count | 16 Ounce | ## Product Details - **Bottle Nipple Type:** Vented - **Brand:** Philips Avent - **Color:** Glass - **Item Weight:** 4 ounces - **Material Type Free:** BPA Free ## Images ![Natural Glass Baby Bottles, Slow Flow, 4 oz, BPA-Free, 4-Pack | Combo Feeding, Baby-Paced Milk Flow, Premium Borosilicate Glass, Easy Sterilizing, Fridge Storage, Slow Flow 2 - Image 1](https://m.media-amazon.com/images/I/71IsWBuTvfL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: What size nipple comes with this set? I see different answers posted??** A: Hello! Philips Avent Glass Natural Response Baby Bottle SCY913/04 comes with a Flow 3 nipple. **Q: I had these bottle for my newborn and I noticed that the ring leaks the milk out. Why? I sterilize my bottles once a day could that be why?** A: I had the same issues, the glass ones need a little care than the plastic ones. 2 reasons,1st you have to align the hole/vent on the ring with the hole/vent of the nipple. Wet the lip of the glass bottle so that when you screw down the ring it fits snug. Most of the times time the leakage happens when the bottle is hot, probably with the glass expanding. But once these are taken care of it never leaked on me. **Q: Can these be used to store pumped milk in the freezer?** A: Yes they can. I have done this with all four of my children and have never had a problem. **Q: Where can I find a bigger nipple size for 6m+ or 9+** A: I have found them at Walmart and Target. But not always in stock so you might have to keep going back and checking ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love these glass bottles!

I understand the risk of glass breaking but if you get the sleeves for them that cuts down that risk by a lot. I’ve never had the nipples on these leak like other brands *cough cough* dr brown’s. And these bottles don’t have a million pieces to clean. So for the money the value is great, I would highly recommend starting off with like size two nipple for newborn, my guy could not get anything out of the size one when he was first born and now on month five he is size 3-4. So easy to use, the sizes are easy 10/10!! ♥️ ## Frequently Bought Together - Philips Avent Natural Glass Baby Bottles with Natural Response Nipples (Slow Flow, Flow 2), 4oz, 4-Pack, SCY910/04 - Philips Avent Natural Response Nipples, Extra Slow Flow (Flow 1), 4-Pack, SCY961/04 - Philips Avent Natural Glass Baby Bottles with Natural Response Nipples (Medium Flow, Flow 3), 8oz, 4-Pack, SCY913/04 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/347144891-natural-glass-baby-bottles-slow-flow-4-oz-bpa-free](https://www.desertcart.jp/products/347144891-natural-glass-baby-bottles-slow-flow-4-oz-bpa-free) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-08*
