Worried about the link between babies bottles and cancer heart disease etc:

I was going to suggest MAM as well. We use them.

Most bottles are [7] because that is polycarbonate plastic - and it stays very clear and is less likely to became hazy or cloudy when washed/sterilised repeatedly.

I loved the avent bottles but they arent coming out with BPA free bottles till next year.Just have to get glass i spose. It is great to see that more places are stocking the glass ones now. I have found them in the chemist, baby shop, target and big w here but yet last time i was preg i couldnt find them anywhere at all.

I use the Nuk plastic bottles and there's a big fat 7 on them. Has anyone ever used the Nuk wide neck teats on any other bottle? My DD#2 won't take any other bottle so its not a case of just changing to a different bottle.

In Canada, those plastic bottles have just been banned. Anything with BPA is not allowed. Glass bottles have been working well for us since then. I have broken a couple when they were dropped on cement outside, but inside, they are just fine. Also, you can get a silicon "sleeve" to protect the bottle if you are going outside. (Toy's R Us carries them here, but otherwise, just google.) Evenflo makes great glass bottles that are really inexpensive. (I think they were like $2.00 a piece, for a 250mL bottle.)
I'd definitely recommend the glass - why take the chance? The bottles are cheaper anyways.
