I'm guessing none of what you've done will take care of the eggs in your carpet that will hatch at some point. (I've never experienced a problem with eggs in bedding, and anything hanging up should not be an issue. I'm guessing toys would only be an issue if they had some kind of pile like carpet where the eggs could be laid.) When I've had fleas in my house and used foggers, I've just left the closet doors open, which kills the actual fleas. The last time we had fleas in one of our rentals (I fogged the place twice, myself), I finally just called an exterminator, because the eggs just kept hatching, resulting in reinfestation. I will never attempt to tackle a flea problem again without calling an exterminator, and they can tell you exactly how long you need to wait before entering the house and allowing a child to come in contact with the carpet.
