A friend just sent me a video of you talking about safety concerns about plastics and children. My wife and I are brand new parents. Our twins were born 6 weeks ago. We are using the Dr. Browns BPA-free bottles. My concern is we’ve been washing them in the dishwasher. I’m wondering about the possibility of substances (other than BPA) in the plastic leaching into the milk due to the heat in the dishwasher. Do you have any info on this? Where do you find your information? We’ve been reading a lot but haven’t seen any studies on possible dangers of BPA free plastics that are exposed to high temperatures. Do you think I should switch to glass or just start hand washing the plastic bottles I’ve got. Thanks for your help.
Congrats on your new additions.
Watching that video of me talking about plastic, it should come as no surprise that I’m deeply wary of plastic for both environmental and health reasons and therefore fond of both shatterproof glass and/or stainless steel–especially for the early years and developmental moments. All plastics degrade when exposed to high temperatures. While the safety research has mainly been on BPA (plastic #7) and PVC/Vinyl (plastic #3), there are studies that have been done on what comes out of even the plastics that are considered safe by the scientific community, especially #1. Since you’re contending with twins, you might not be aware that the FDA recently finally banned BPA from baby bottles, though not from any other infant products (which is frustrating). There is no word on what manufacturers are supposed to be replacing BPA with, and if these chemicals are any safer than their banned predecessors. More reasons to avoid plastic….
Though there are great resources (like The Environmental Working Group) to turn to for information on plastic, staying on top of the latest plastic safety details can be a full time job. This is another reason I prefer glass and stainless steel. You don’t have to keep on top of their safety.
Another bonus: If you are too tired to wash everything by hand, glass and stainless are your friends; both are fine in dishwasher. Keep in mind that any/all plastic you use should only ever go on the top rack of the dishwasher if you can’t hand wash.
Bottle issue solved, now get some sleep!
