BPA-free bottles or not??
I reproduce what 2 other mums said on this topic.
Mum 1: "Hmm, there are several things in consideration for BPA. Firstly, its actual toxicity. It has been tested in lab mice at various concentrations and in some studies proved to be harmless to reproduction even at high levels (but do other damages). There are some studies that showed it may exacerbate cancers. It is found to have higher potency in the test-tubes then in-vivo so maybe the body has some way of metabolizing (neutralizing) it. Again, all these studies done in mice. Remember their size in comparison to humans. I dun think any of these studies did a relative size - dose thing.
Secondly, the other thing to consider is the release of BPA. How much of it really leech from the bottles into the water? I haven't seen much studies with regards to this but then I haven't got the time to even look through all the titles yet.
Hmm, my conclusion in my brief 10 - 15 mins research is that, if you have the money, go ahead to change for a peace of mind, if you dun have the money, dun need to feel bad at all about not changing cuz it may well that BPA is not toxic to humans at whichever level it is leeching into the water. Besides, we have all been exposed to it already, one way or another."
Mum 2: "no worry about the bottles, but dun use OLd bottles, and dun use them for a long time like years. i think every 3-6 months is a good gauge.
If you steam or sterilise your bottles everyday, then discard them slightly earlier lor. i actually steam my bottles only once a month now, or every 3 weeks. nanny steam them every week, but i close my eyes la.
My stand:
chemicals are everywhere now, this BPA is another small chemicals which is SUSPECT to cause this and that but not many studies actually CONFIRm this, u see. everything is also suspected suspected, high chance high chance. Glass bottles are also putting our bb at risk if there is any crack etc? which one is more serious?
I believe our bodies are able to discard and handle these chemicals at very small amount.
I weigh between these bottles(milk bags) vs glass bottles last time, i decided to use milk bag instead cause the glass chips might cause immediate death to my baby if it is very serious. this BPA thing seems less serious liao.
For example, the study stated that BPA will make the immune system worst. so for those baby who fall sick easily, if they use glassbottle then will the problem go away? i dun think so. even if there is, the % will be very insignificant."
