> For baby bottles... I guess the search is on for the next best type of bottle.
Glass bottles for newborns as they can be easily sterilised, and be sure they have a silicone nipple that also forms the seal to the glass of the bottle.
Once they get old enough to use their own, use the playtex disposable liners. No sterilisation or cleaning required, so you only have to do the nipples, which by this age can be just soap and water.
The Think Baby non-polycarbonate bottles appear the best for a rigid bottle, but personally I wouldn't trust something that's going to be washed extremely frequently, scrubbed with brushes or thrown in a dishwasher. You use them for up to 3-4 years, so I wouldn't trust reusing a bottle as it will age.
The playtex liners was below the detection threshold on their test, which was to put boiling water in them and then hold the temperature at 60C for 2 hours. For me that's more than safe enough for the 35C milk I'm putting in it for my kid to drink within 2 minutes.
I honestly think disposable is the way to go, because it eliminates the risk of the materials degrading. These tests are on new, not 1 year old, so the only ones that are valid in every use scenario are the disposable ones.
the argument is chemical degradation with age, not physical abrasion. You leave plastic out in the sun and reactions occur that can depolymerize the plastic, releasing monomeric components. In the case of polycarbonate, those components include bisphenol.
