There have been recent studies that show that plastics leach into our food and can be hormone disrupters.  It is thought that heating food in plastic can be especially dangerous.  The problematic chemical is called Bisphenol-A and is found in most plastic baby bottles. advises consumers to avoid Avent, Dr. Brown’s, First Years, Munchkin, and Umix brand bottles.  Polypropolene bottles are considered safe, but avoid those that have a cloudy appearance and/or are squeezable (Medela, Sassy, and do not make bottles with BPA).  You can get glass bottles from Evenflo or BornFree to be completely safe.

If that wasn’t enough to worry about when picking bottles for your child, breastfeeding mothers should remember these tips to avoid nipple confusion:

  • Always use slow flow (newborn, or Level 1) nipples – even as baby ages
  • Use a long nipple with a wide base
  • Wait until breastfeeding is well-established and baby is at least 4 weeks old
  • Have your partner do the bottle-feeding so that baby doesn’t get mixed messages from mom
  • Follow these tips for positioning, etc.
  • Even better, use alternate methods of supplemental feeding

Don’t forget to pump each time your baby takes a bottle to keep your supply up.

We use Playtex Ventaire bottles (which are polypropolene) with the NaturalShape Wide silicone nipples.  Jack only gets bottles at daycare and when he is home with his dad on Fridays (or during the few occasions that I manage to get some free time on weekends).  I have only tried to give him a bottle once, while we were on a car trip, and he refused to take it.  That was just fine with me!

  1. Wow, I had no idea about this. Why isn’t this talked about more?

    I understand that those Platex bottles can be a pain in the butt to put formula in (because they’re not straight). What do you think about that?

    And out of curiosity (I’ll be a new mom in August), what pump do you/have you used? I was planning on picking up an Avent system, but if I shouldn’t be using the bottles…

  2. I’m not sure (maybe because so much of our lives are built on the use of plastics?). It’s been creeping into the mainstream more often, though. One of my favorite blog writers has a whole series of posts about plastics (linked on her sidebar). My local lactation group also talked about it with regard to bottles.

    I have very limited experience with formula, but I would think it wouldn’t be too difficult to mix in the wide bottles (the narrower ones could be difficult, though). And perhaps formula could be shaken to be mixed (no idea here)?

    I use an Ameda Purely Yours. How often will you be pumping? If you are going to work and be pumping daily, you really shouldn’t get anything other than an Ameda or a Medela Pump in Style (they are the only two that are recommended for frequent pumping). The Ameda can be found cheaper (also sold under the brand name Lansinoh), and one of the benefits is the tubing doesn’t ever get clogged with milk (because of this, some people feel comfortable buying second-hand and just getting new accessories). If you will only be pumping occasionally, the Avent Isis is great (I have two). You can always just pour the milk into a different container for storage. I do use Avent bottles to store milk and just avoid heating them. They are the only bottles I’ve found big enough to hold the amount of milk my son takes at daycare (~9 ounces).

  3. I use these

    I’ve been lucky with Rheya…I introduced a bottle (of expressed milk) when Rheya was 3 weeks old…I’ve never had nipple confusion, and she takes bottles from me just fine.

    You just answered a question I’ve been asking for the past month and a half “Always use slow flow (newborn, or Level 1) nipples – even as baby ages” I’ve been looking for this information in books and on the web for ages! I bought the 3-6mnth teats but never opened them because I was worried the faster flow would make her lazy.

    Nearly finished reading your blog…woo 9 months worth of diary in 3 days…haha

  4. I’ll look up that link, and see if I can find some more information. It just seems… wrong that if a company KNOWS that their products cause health problems that (I assume) would end in a lifetime of problems, that they would do something about it. I mean, it’s not rocket science (in my completely unknowing opinion).

    So… is it just bad to heat the bottles? Is that the issue?

    And, the question about the formula is just because most people scoop the powder and dump it into the bottle using one hand – I guess you could just tilt the bottle to get the powder in there without making a mess, provided you can put the baby down. The issue is the getting the powder into the bottle – not mixing. 🙂 I’m sure that it’s done all the time. 🙂

    I plan on pumping only when necessary, like if I want to go out for an evening baby-free once she’s established good breastfeeding habits. So, maybe not enough to invest in a fancy electronic system. I was thinking about getting the Avent Isis system (the hand pump), but wasn’t sure if it’s “ok” because of the plastic thing.

  5. Here is some more information on it. Plastic leaches regardless, but heating the plastic speeds up the process. Unfortunately for us, by the time I found out about this, we had already introduced Jack to a bottle and he gets pissed if we try to give him a different type of bottle. We might need to try again, though. I also try to limit our use of plastics in other areas. Unfortunately, plastics are everywhere! And, it’s sad, but this information has been out for at least 2 years now. I know that the UK has banned plastics from being used in cosmetics…why this isn’t more widespread is a mystery to me, as well.

    As far as pumps go, Medela makes a Single Electric Pump. I don’t know what the pricing is on it, but it would be worth checking it out.

  6. I also had a medela pump and the dial on it (to make pumping slower/faster broke. I then bought the Avent Isis electric pump and I love it! It’s served me well so far.
