Finally there is an ordinary glass bottle for the baby. After several plastic bottles I bought the glass bottle and am very satisfied. So must be a water bottle for babies. You can be really good clean and although it is a bit heavier, I'd want to trade any more. The plastic bottles from Avent I bought a few weeks ago, already put down a discoloration that no longer goes out, no matter how you scrub. Glass bottles are safe and healthy, the market but unfortunately swamped by plastic toys for babies. More such products Avent!
