Also, never allow a baby to play with your keys; many keys have lead in them to make them pliable. Since babies will likely put the keys in their mouth, they are susceptible to lead poisoning.
Think "less is more" when buying newborns toys to play with. Look for organic, unbleached plush toys, unpainted wooden blocks, decorative accessories and polyvinyl chloride-free (PVC-free) or plastic-free toys. Look for bibs, playmats and placemats that are also PVC-free and, if possible, 100 percent certified organic cotton.
When buying a crib mattress, look for one that is completely free of polyvinyl chloride -- a waterproof material that has been linked to off-gassing chemicals. The baby's immune system is still developing at a very young age, so choose a crib mattress made with chemical-free natural materials. Natural latex, soy-enhanced foam, organic cotton and organic wool are healthier choices are for your baby.
