## Overview

## Description

5 Phases is the first bottle feeding system to introduce an interchangeable glass insert. Our unique design kept theca-mom in mind providing the healthful benefits of glass +the protection of BPA free plastic all while reducing the carbon footprint on the environment. Our "grow with me "feeding system truly makes our bottles the most eco-friendly bottle feeding system out there. Recent studies show there are health concerns associated with any plastic - even BPA free plastics. Having baby feed from GLASS reassures parents their babies are drinking from the purest bottle possible. Though the medical community is increasingly recommending GLASS over plastic, many parents are hesitant to use glass bottles in fear of them breaking. Our eco-friendly bottles provide the perfect solution. The "interchangeable glass insert concept" is one of a kind. The recyclable translucent plastic sleeve guards against breakage but contains the broken glass and liquid mess if breaking occurs making it safer alternative in glass bottle feeding. The ability to buy additional glass inserts adds convenience and affordability and reduces the carbon footprint in the environment because you use less plastic. A perfect storage solution for pumped milk and formulas, our glass inserts "grow with me" feeding system are ideal for homemade baby food when baby has moved on from their bottles. Now that's eco- friendly. 2015 New York Family Magazine Best Bottle Picks2014 American Baby Best Bottle Picks.

    The best of both worlds
  

*by N***R on Reviewed in the United States 🇺🇸 on July 7, 2012*

We were thrilled to come across this product. Our daycare doesn't accept glass bottles and was less thrilled with stainless steel (and there are also some lingering issues about just how much will leach from stainless). They have no problem with these bottles and have actually remarked that they wish that something like this had been available for their children.Our daughter is fine with the nipple that comes with the bottle. It did take her one or two tries to get used to it though that was expected as it was a very different shape and size from what she had been using. The nipple base is a less common size so you are more limited in options if you find that the nipple doesn't work. We have found that the nipples leak very little which is generally good though challenging if you're used to testing milk temp - just squeeze lightly and out it will come.There are two primary areas where the design could be improved. First, there are not many threads on the base (or cap) so that you only have just over one turn to secure it in place. You have to be careful to get it on or else it could pop off. I find myself backthreading to make sure that it's seated well and then turning down. We haven't had any problems with leaking once the cap is actually on. (And it's pretty clear that it's not seated well otherwise.)Less critical is that the volume markings are somewhat variable between bottles and not super accurate. They're in the right vicinity but off by enough that you notice. (Ours all read slightly less than what's actually in there.) In general, they have a look and feel (up close) that seems a little cheaper than one would expect given the price (though the nipple seems very good quality and durability). We've only had ours a couple weeks, though, so can't say for sure how they'll hold up. We hand wash ours, though, so I'm not overly concerned at this point.** Update ** After two months of use, we're still generally satisfied with these. We have had one bottle that somehow completely emptied because of a leak (they have to store them largely on their side at daycare as they are too tall to stand upright). Small leaks once or twice though not substantial amounts. In general they seem to be holding up well and are showing little signs of wear.

    I originally loved the bottle, but....
  

*by S***F on Reviewed in the United States 🇺🇸 on January 4, 2015*

I never before wrote a review that was not a 5 or 1 star.When I was reading reviews for this bottle, I was really excited. Originally I got 2 of them (different sizes) from my baby registry, then bought this bigger one myself. The nipple on the smaller bottle was awesome! barely anything could get through, but the bigger bottles, even though still same nipple were letting out much more milk.Overall, about 2 months ago I would have given this bottle 5 stars, BUT, since then 2 glass inserts are gone since they are too fragile. So I would like to outline the "cons" for this bottle:-expensive-replacement inserts can only be purchased on 5 phases website, and they do not have free shipping on every order, only 70+-extremely fragile glassPros:- easy to read measurements- nice to hold design- very good for heating milk in hot water (kiinde)After 4 months of using bottles - I prefer lifefactory glass bottles.

*by B***E on Reviewed in the United States 🇺🇸 on September 18, 2014*

While I think this idea of having a glass bottle inside of a plastic one is brilliant, there are a few things about this one that should be fixed.Pros:-It's glass, I don't have to worry about leaching God knows what into my little one's food-Plastic on the outside, so smart, it protects it pretty well-Generally the nipple and cap screw on with few problems, only occasionally have I had it leak on meCons:-The nipple doesn't really hold it's shape, whenever my baby's eating the tip of the nipple kind of sinks into the rest of it making it hard for him to latch-The glass isn't tempered so you can't pour boiled water and then cool it with boiled ice cubes.  Annoying.-A small mouth, hard to mix formula in (not impossible, just kind of annoying)All in all, great concept, I hope they continue to tweak the product, but until then, I'll stick with my Born Free bottles.
