I used to have lots of plastic baby toys. First I got rid of all the soft plastic toys (in case they were made of vinyl and contained phthalates), then I got rid of all the plastic toys except those that I knew were made of "safe" plastics. But in the end, I decided to banish all the plastic baby toys. I found that when I had plastic as well as natural toys, I often had to watch my baby favor the plastic ones. But for my babies who never got to suck on plastic, I've found they like the natural toys plenty.
Since babies spend so much time with their hands and their toys in their mouths, and since babies are especially vulnerable to synthetic chemicals, why mess around with plastics? These days there are tons of awesome teethers, rattles, stuffed animals, blocks and other toys for babies made of cotton, wool, bamboo, wood and other natural materials. Here are some of my third baby's favorite teethers:
