Top eco-friendly baby bottles

Since my family and the families of a number of my girlfriends will be expanding in the coming year, I thought it was a good time to start researching baby products again. The great baby gear up begins with baby bottles.

In our house we have bought new sets of baby bottles for each child as the design and safety standards change so frequently. Here are a few bottles that got great reviews from around the Internet:

BornFree 

The bottles are leak proof and BPA Free.  The bottles are made to flow liquid only when the baby "suckles", BornFree calls that feature ActiveFlow. According to their website, "ActiveFlow where babies control their own flow of milk, makes for a comfortable and easy feed for both of you while combining naturally while breastfeeding." The company did a clinical study this year which states use of the bottle helps reduce colic.

thinkbaby 

The thinkbaby was founded by Kevin Brodwick. Brodwick, "brought his interest in health and preventative medicine and his background in biotechnology together to form a company whose sole purpose is to create alternative products for little ones to adults." (thinkbaby.com).

I love the color of the bottles. I also love that they are divided into stages which helps transition the baby from bottle to sippy cup.  They also are super reasonably priced.

The bottles are BPA free, dishwasher safe, feature cross-cut nipples which help develop the baby's proper sucking mechanism.  They also feature a special vent system that helps reduce gas, colic and inner ear infections.

Green to Grow

These bottles are made of BPA free plastic named PES.  PES helps keeps the bottles clear and free from odors unlike other types of plastics. They are also free of PVC, lead, and nitrosamines. I like their design however I am not sure about the $10.00 per bottle price point.

Have you used any of these bottles? Or do you use another Eco-friendly baby bottle?
