Would you consider using stainless steel instead of glass? I find it safer and more durable. In fact I wish I found it earlier because I think I could probably use these to death! http://www.purastainless.com/products/infants/
Bot a couple for my kids at mothercare. Teats are excellent, my toddler bit thru nuk teats every 2-3 weeks and hasn't been able to bite thru the sippy teat for this. I regret stocking up on so many nuk bottles cos I read that even if the bottles are bpa-free, they can still leech other forms of bad substances.
You don't get that with glass but glass might break and hurt someone..
