The California Public Interest Research Group, CALPIRG, says one construction kit is approved for sale, but contains parts small enough for a child 3 years and under to swallow.
"Well the first thing that I would recommend is to using an empty toilet paper roll as a test tube to see if a toy is too small for a child ages 3 and under. So a parent can take an empty toilet paper roll and if a toy fits inside its too small for a child younger than 3 years or age," says Austin Price from CALPIRG.
CALPIRG says another backpack contains dangerous levels of phalates, but not the kind currently regulated by California law. It recommends avoiding soft plastics and buying an inexpensive lead testing kit at your local hardware store.
