Philips AVENT 4 Ounce Natural Glass Bottle, 1-Pack

First off I wanted to say how glad I am to see that Avent finally decided to produce a bottle in glass. I am about to have baby number three, and I loved Avent bottles with my other two kids. After my first son was diagnosed with childhood cancer however, I decided that we needed to make some changes for our second son. Maybe this is overkill -- probably it is -- but making a few changes helped me to feel better about the amount of chemicals we were exposing out kids to.That said, we decided after I quit nursing that we'd devote ourselves to using glass bottles since it was the one thing our son's food would constantly be in contact with. We tried Evenflo, Munchkin, BornFree, and Dr. Brown's glass bottles. The Evenflo and Munchkin bottles would frustrate our son because the nipples constantly collapsed, the BornFree and the Dr. Brown's each had five(!) parts to hand wash (who has time for that when you have two toddlers), and sometimes with the Dr. Brown, no matter how well we cleaned them, we'd occasionally find mold growing on the inner yellow piece, not to mention the venting funnel apparatus was plastic (kind of defeating my avoiding plastics purpose there). I had a few Avent bottles that I loved and would occasionally use when I would get so frustrated with the glass, but then I would feel guilty for using the plastic. I always hoped that they would eventually make them in glass, but they never did while my other two were still bottle feeding.When I saw that they were finally making a glass Avent bottle, I excitedly pre-ordered one for our newest addition. I got only one four-ounce bottle because I was afraid it wouldn't live up to my long awaited expectations. I'm pleased to say that upon initial inspection it's everything I hoped it would be. It's three simple parts, and most importantly, the nipple itself is vented so that it won't collapse during feeding. In comparison to the current Avent polypropylene bottles, it stands the same exact height, but the bottle itself is wider by at least a good centimeter. It has a more pronounced curve and is obviously wider to accommodate the thicker glass. The glass itself is substantial enough that I don't worry about breakage, however it does add some weight to the bottle. I guess it's about as thick as a canning jar, maybe a little bit thicker actually. The lip on the inside of the mouth of the bottle has been somewhat rounded and I appreciate that little detail because on some bottles it's almost sharp to the touch when washing.The nipples on this the new "natural" line have been changed. The inside of the nipple no longer has two lips (which I think was how they originally achieved nipple only venting), and you no longer have to insert the external ring to keep the bottle from leaking (classic polypropylene version only). I tried to interchange the nipple from the four ounce classic polypropylene bottle to the new natural bottle and it doesn't fit. The older nipples are now about 5mms smaller, therefore they just fall out of the new ring. It appears that the mouths of the bottles are still the same size, so you might be able to put both rings on both bottles if you have the correct nipple in the correct ring and switched only the body. I will say though, that when I tried to switch the two, I would occasionally get leakage from the older bottle/new nipple combination. The instructions that came with the bottle state "only use Philips Avent Natural nipples with Philips Avent Natural feeding bottles" and "do not mix classic bottle parts and nipples with parts of the Natural bottle, they may not fit and could cause leakage."When filled with liquid, I've tried every thing I can think of to try to make it leak, but it doesn't leak at all. This bottle came with a stage 1 nipple for newborn up and when held upside downward it doesn't drip liquid at all. For comparison, I have a brand new classic Avent polypropylene bottle with stage 1 nipple that I just tested and it dripped considerably when held upside down.The only reservation I have at all about this bottle is that the measuring marks on the side of the bottle are painted on to the glass. I would have liked the markings to have been molded into the glass like the Evenflo bottles are. From past experience with painted on measurements (BornFree glass), they usually will wash away over time. I don't know if this will be the case with these bottles as only time and frequent washing will tell, but my suspicions are that they will.As a side note, the instructions bring up the point that these bottles may not fit in a standard warmer. As well, they make special note to say that if you are using an older Avent sterilizer, you need to go to their website and get special instructions on how to place new Natural bottles. Another point they mention is that the glass bottles are only compatible with Avent breast pumps and sealing discs, but for safety reasons, not for use with the trainer spouts and handles.Overall I really like these, and I have already ordered more. When our newest addition arrives in a few weeks, I will update more with extended user experience.

It seems like we live in a world of plastic these days; so naturally, I was thrilled to find out that there is still a demand for glass baby bottles out there! We have used Philips Avent Natural Glass and Plastic bottles (4 oz) and the Medela (5 oz) plastic bottles. Call me old fashioned but I prefer using glass bottles versus plastic ones. The glass bottles have a sturdier feel to them when compared to plastic and don't soften or flex when boiled. They have a crystal clear appearance when cleaned and don’t develop the cloudy appearance that some plastic bottles do when boiled over time.The product consists of 4 parts, a cap, a ring, a nipple and the 4 oz glass bottle. The nipple that the Avent Glass bottle comes with is the Natural Newborn flow nipple. These are the best nipples in my opinion. They don’t collapse and are great at ensuring that the baby feeds comfortably. Ive tried using the Medela nipples/bottles but even with the slow flow nipples my little one tends to choke more often when drinking from them.The Avent bottle’s wide neck makes cleaning very easy. Ive used both the Avent and Playtex brushes to clean these bottles; both work great. Sterilizing them is easy too. Ive been boiling them as per the instruction booklet that comes with the product. Don’t forget to sterilize them before first use too. The measurement guide on the side of the bottle is legible and does not fade away after boiling/sterilizing the bottles.Some reviewers have complained about the ring not fitting onto the bottle properly. I find this to be an unfair assessment. I’ve purchased 5 of the Avent Natural Glass bottles and have never had an issue with placing the rings/nipples on the bottles and have never had an incident where the bottles have leaked.If you can get past the fact that the glass bottles are heavier than the plastic ones then I would definitely recommend the Avent Natural Glass Bottles with the Newborn Flow nipples.

I chose these bottles after having a bad experience with a few other well known plastic brands. The main reason I switched to glass was because the plastic bottles never seemed to be clean after both boiling and washing. I was having a problem with the different plastics developing an odor over time regardless of how often I would thoroughly rinse and wash them immediately after feedings. I chose these glass bottles because the nipple seemed to be the most natural shaped compared to other glass bottles available.The only dislikes I have about these bottles is the fact that there is no real resistance in the nipple when my son is drinking, so he chugs it down. It would be nice if the nipple were truly slow flow because breastfed babies are used to working for their milk. My son is eight months old and we are still using the newborn nipple because it seems to have the slowest flow of avent nipples. Until I find a better nipple that fits these bottles I just have to tip the bottle away from him for a few seconds so he can pace his intake.And my second dislike or at least caution to other parents is make sure that if your baby is starting to get drowsy while drinking that you are helping to hold the bottle that way it doesn't drop on your baby when they fall asleep, these bottles are pretty heavy and could hurt if dropped.Overall though these are my favorite bottles so far, I just wish I would have found them sooner.

This is a very good product as it is good quality glass, and BPA free. I don't want to use plastic bottles for my 2 month old as I don't think it is safe due to possible plastic toxicity. These glass bottles are quite hard to find though in the UK, which is a shame.

Very good quality and worth the money.
