Born Free 9 oz. BPA-Free Decorated Bottle, 1-Pack

We are on our second baby with the Born Free bottle system. We had no complaints the first time and still had a lot of bottle so it made sense to use it for the second kid. All the bottles we had were the Classic version, this is the original amber colored polycarbonate bottle. When I needed a few extra bottles the Deco bottles seemed like an good choice at 30% less than the Classic bottles. After a month of use I can say the Deco bottle would be a good choice except for one significant flaw.The key point here is the ONLY difference between the Classic and Deco bottles is the bottle materials, the valve parts, caps, nipples, etc are 100% the same. After a month of use the Deco bottles are wearing just as well as the Classic bottles also.The Classic bottle itself is polycarbonate (PC) and the Deco bottle is polypropylene (PP). The only published difference is that the PC bottle can be heat sterilized (autoclave) and the PP bottle cannot. This makes sense as can PC handle much higher temps than PP.The unadvertised difference is that the Deco PP bottle heats much slower than the Classic PC bottle. The first few times we used the Deco bottle I just thought i was judging time poorly. After a few uses though it was obvious that the Deco bottles were heating much more slowly.So I did a little experiment to see how different it was. I took one Classic and one Deco bottle, filled them with 8oz of water and placed them in the fridge until cooled. The water measured 44.4F at the start of heating. They each went into their own identical room temperature ceramic bowl and the bowl was then filled to the brim with 210F water (about 16oz). This is our standard bottle heating method. Then I measured the temperature of the water in the bottle as they heated to 98.6F.End results the Classic bottle took 5m45s to heat to 98.6F and the Deco PP bottle took 11m14s. Any parent will tell you five and half minutes is an eternity with a hungry baby.In conclusion if you don't need to heat cold bottles for feeding or you plan far enough ahead that 11 minutes seems OK to you then the Deco bottles are an excellent choice. But I think saving over 5 minutes everytime I heat a bottle is worth the extra money spent on the Classic bottles.Notes:Here is the data from the test: [...]I wish I had a good idea for the cause of this difference. If you look at the thermal conductivity of the materials I should be seeing the opposite effect. PC has an average thermal conductivity of 0.184 W/m-K and PP is 0.245W/m-K. So the PP bottle should be transfering heat faster than the PC bottle.[...][...]

These bottles do a decent job of reducing air ingested while also being easier to clean than say, the Dr. Brown's bottles. The bottles have a plastic disc and silicone membrane that fit over the rim of the bottle before the nipple is screwed on. These two pieces are a bit difficult to get apart for cleaning, as the fit is snug. For my daughter I did not see any difference in air ingestion between these bottles and those with an easier to use/clean venting system (Avent, Tommee Tippee). I like that the markings on the side are easy to see and read, although I would prefer they had the 1 ounce level marked in some way - they only have 2,3,4, and 5 ounces marked.The nipple flow on these bottles always seemed to be a bit of an issue - as a newborn my daughter would leak milk out the sides of her mouth (she did this with all bottles I tried, but the Born Free were the worst), and now at 3 months, she is making a clicking noise when she swallows, which I think means we need to move to a higher flow. I feel like these nipples went from being to fast for her to too slow, with nothing in between.In regards to the two type of bottles offered - I have a set of the classic bottles and a set of the deco bottles. The pieces are fully interchangeable between the two. I was surprised to find the deco bottles are significantly larger than the classic bottles, although both hold 5 ounces. I find because of the large size the deco bottles are harder to comfortable hold while feeding a newborn. It is more difficult to cuddle the baby in close to you for feeding when the bottle is as large as her chest. I can't see any reason why the deco would be larger than the classic, and if I were to order another set I would definitely get the classic.

Soon after my son was born, it became clear that breast feeding was not going to work out, so I started researching formula and bottles when he was around a week old. I decided to try the Avent bottles first after my lactation consultant recommended them. From day one, we had issues with spit up, gulping/choking, leaking, and gas but I really wanted to give them a shot (after all, he was completely new to the bottle and I figured there'd be a learning curve for both of us) and at least get my money's worth. We used them from the time he was one week old until he turned five weeks old. For a short while it seemed like things were getting better, but we were still dealing with a lot of spit up, gas, and wasted formula. After reading some great reviews about the Born Free bottles, I decided to try them next. We've been using them for several days now, and so far I'm pleased with them. My son seems to be able to latch on better, which means he's squirting less formula out of the corners of his mouth. He doesn't choke anymore and he generally gulps less (which means he's taking in less air). Lastly, he went from spitting up at every single feeding (and we're not talking little dribbles here and there - he would expel large amounts of his meals forcefully, very similar to vomiting) virtually no spit up. He seems to burp just as much, but with much less effort and, like I said before, MUCH less spit up. Not perfect, but definitely better. I took off a star because the bottles are bulkier than the Avent bottles, and it makes feeding awkward (I like to cuddle him close during feedings). Also, cleaning takes a bit longer because of the more complicated system.Overall, we're happy with the transition and I think we've found the bottle that works for us!
