Plastic baby bottles have come a long way in recent years and they are now unlikely to contain significant amounts of BPA or phthalates.
Glass is a naturally non-toxic and safe material, but when choosing glass baby bottles, one factor to be mindful of is the potential for lead in the painted logos. Testing has found that certain brands have high levels of lead in the paint on the outside of the bottle. Although this paint does not come into contact with milk, it can rub off onto babies hands and then get ingested.
Even so, glass remains the best option for use at home because some plastic baby bottles have been found to contain related bisphenol compounds and they may release microplastics, particularly when heated or damaged. For that reason, it is best to use glass when you can and to treat plastic bottles gently if you need to use them.
The Best Glass Baby Bottles
Fortunately there has been extensive testing of glass baby bottles in recent years, with results reported by Tamara Rubin of Lead Safe Mama and Eric Ritter of Detectlead.com. According to this testing, the best brands of lead-safe glass baby bottles are shown below. If you live in a country where these brands are not available, look for glass baby bottles with little to no decorative paint.
