Recently, I started looking into plastics and how they are used in our foods. And I stumbled upon an article called
"Smart Plastics Guide." In it they describe all of the different kinds of plastics and their uses. It's incredibly resourceful. I plan to take a good look at all of the plastics that we use for our food.
But I started with the bottles that we use for Addie. I've always been an Avent user. I have all of the bottle nippes (all of them!). And I have a ton of different bottles for them. Avent bottles are made out of Polycarbonate. Bisphenol A is found in Polycarbonate. Here is what the article says about it:
Bisphenol A (BPA), a chemical that mimics the
action of the human hormone estrogen, can leach
from polycarbonate plastic.3 Human exposure to BPA
is widespread. A Centers for Disease Control study detected
BPA in the urine of 95 percent of adults sampled.4
Scientists have measured BPA in the blood of pregnant
women, in umbilical cord blood and in the placenta, all at
levels demonstrated in animals to alter development.5,6
Hormones stimulate certain cancers. Bisphenol A has
been found to stimulate prostate cancer cells7 and causes
breast tissue changes in mice that resemble early stages
of breast cancer in both mice and humans.8,9 One study
found an association between ovarian dysfunction and
higher levels of BPA in urine.10
So, I read on in the article and they said this:
Use alternatives to polycarbonate plastic baby bottles and “sippy” cups. Knowing what we do about BPA leaching and the real risks to children’s health, you might be surprised to learn that most plastic baby bottles and many “training” or “sippy” cup sare made of polycarbonate. Fortunately there are alternatives, including baby bottles made of glass, polyethylene or polypropylene. Those made of pliable, milky-colored plastic contain no polycarbonates. Usually baby bottles are not labeled, so if you have questions about the type of plastic used, call the company’s toll-free number listed on the package.
And to apply this to our lives:
More on baby bottles and “sippy” cups
Avoid: Polycarbonate product examples
- Bottles: Avent; Dr. Brown’s; Evenfl o (clear); First Years; Gerber (clear); Playtex Vent Aire; Sassy; TupperCare
- “Sippy” cups: Gerber Suzy’s Zoo & Sippy Snacker, Playtex First Sipster & Sparkling Sipster
Safer alternatives: Non- polycarbonate product examples
- Bottles: Evenflo glass or pastel polyethylene plastic; Gerber polypropylene opaque plastic; Medela breastmilk polypropylene storage bottles and polyethylene milk storage bags; disposable bottle systems with polyethylene plastic inserts (e.g., Playtex Nurser, Playtex Drop-Ins)
- “Sippy” cups made of polypropylene or polyethylene: Avent Magic Cup; Evenflo cups (inner lining); First Years Take & Toss; Gerber Color Change, Sport Fun Grip and Soft Starter; Playtex Sipster, Big Sipster & Quick Straw
Baby bottle nipples are usually made of silicone or latex
rubber. Silicone nipples are lighter in color and are safer, as latex
rubber nipples may leach carcinogenic nitrosamines.22

So, I've decided to stop using my Avent bottles and other clear plastic ones. And now I'm using the disposable drop-in liners. I'm using the Playtex bottles, and Avent disposable bottles. Apparently, Avent just came out with a new drop-in system called the
Tempo and it uses the polyethylene liners. So, those are the bottles that I'll be using. If this was my first, I might consider switching to glass bottles, but I just can't afford the expense of replacing all of our bottles and nipples with a whole new system.

And thankfully, we've been using the First Years Take & Toss cups a lot recently, so those are safer ones as well.

If I had a ton of money, I would use
Kleen Kanteen stainless steel cups with the Avent adapter. It allows you to use Avent sippy tops or Avent nipples with their cups - a very safe alternative.
I do have to say that Avent does have a disclaimer on their website which discusses Bisphenol-A and it's safety. So, it's up to you who to believe. Just letting you know what I've decided to do for my family.
