Natural Glass Baby Bottles with Natural Response Nipples (Slow Flow, Flow 2), 4oz, 4-Pack, SCY910/04

I’m really happy with the Philips Avent Natural Glass Baby Bottles with Natural Response Nipples. The glass feels high-quality and sturdy, and I love that it doesn’t hold odors or stains the way plastic sometimes does. The Natural Response nipples are great—my baby transitioned to them easily, and the medium-flow (Flow 3) is perfect for comfortable feeding without leaks or choking. The bottles are easy to clean, easy to assemble, and the shape makes them comfortable to hold during longer feeds. I also appreciate that they heat up evenly and cool down quickly. Overall, this 4-pack is absolutely worth it. If you’re looking for durable, safe, and baby-friendly bottles, these are an excellent choice.

nipple offers a breastfeeding-like feeding experience by only letting milk flow when the baby actively sucks, which helps mimic the natural suck–swallow–breathe rhythm and may make it easier to switch between breast and bottle. Many users appreciate its thick, durable glass construction that’s easy to clean and doesn’t retain odors, and the wide neck and simple parts make sterilizing a breeze. On the downside, several parents report that the lid can leak if not assembled perfectly, and some feel the flow from the Natural Response nipple is too slow even frustrating for babies, particularly early on.

These are very surdy bottles and I'm not worried about them breaking. The flow rate was excellent for my baby as a newborn and when I felt she needed a faster flow, I got level 5 nipples. The milk doesn't drop out when you tip the bottle which is amazing! I tried comotomo bottles and they dripped and my baby didn't like them. I know different babies like different bottles, but these were perfect for us. I feel comfortable with the materials, they are easy to clean, well designed, and well made.

We absolutely love these Philips Avent Natural Glass Bottles. The glass is easy to clean and sanitize, and I appreciate that they are made without plastic. The natural-response nipple really helps baby control the pace, making the transition from breast to bottle (and back) seamless. We have had zero issues with confusion or excessive air intake thanks to the anti-colic valve. They are durable and feel high-quality. A wonderful set for newborns!

We switched from Dr. Brown’s bottles to these and have been very happy with the change. Milk only flows when the baby actively sucks, which has dramatically reduced leaks, mess, and wasted milk. The nipple design feels very natural, and our baby transitioned easily between breastfeeding and bottle feeding. One thing to note: coming from Dr. Brown’s Level 1 nipples, we did need to switch to a Flow 3 nipple with these bottles for a comfortable feeding pace. The only minor drawbacks: • At around $10 per glass bottle, they’re on the expensive side, though most comparable bottles in this category are similarly priced. • Protective sleeves are sold separately and add another $3–$4 per bottle. • The nipple ring threads are generally fine but occasionally need re-threading to sit perfectly. Overall, these are excellent bottles. Despite the cost, the performance, reduced milk waste, and smooth breast-to-bottle transition make them well worth it. Highly recommended.

Cleans really well, have dropped one by accident and it did not brake. Does not hold smell like plastic would. Lost one under the seat in the car finally found it two days later. It rolled to the very back of the car. There was no smell of sour milk after it was cleaned. The nipple had to be thrown away but the better than the whole bottle holding on to that sour milk smell.

This glass baby bottle won me over from the very first use. The quality feels excellent: the glass is thick, durable, and very easy to sterilize, which gives me great peace of mind when feeding my baby. In addition, it doesn’t retain odors or stains like other materials, so it always stays looking like new.

Long time glass bottle user with all 4 kids. Baby loves these. They clean great. It’s nice not to worry about warming bottles and scratches causing chemical leaching. I have let my babies use these past 9 months when they start chucking them. We have broke probably 100$ worth in bottles. But I keep rebuying for new babies in the family because they are safer and better for their health. Wish they would sell them honestly for more money with decent silicone protectors. The ones they make to protect advents are very thin. These bottles shatter on kitchen tile, so fine being tossed out of a crib onto wood floors.
