Why choose glass baby bottles?

Over the years, the risks associated with using plastic baby bottles have come to light. An article by Harvard Medical School reported that leaching from plastic could occur even faster and greater when exposed to heat. On the other hand, borosilicate glass is made from natural raw materials (liquid sand) and is inert, meaning it cannot leach, even at high temperatures.
Generally, PP plastic baby bottles are only designed to last for a few months as they degrade quickly, stain and harbour odours over time. Borosilicate glass does not degrade, stain, is scratch resistant and non-porous, so it will not hold odours. Within the lifespan of one glass bottle, you may well have purchased six plastic ones.
