"Nanny" laws and rules

Can someone please tell me these are urban legends:

(A) Local licensing authorities outlawed soap in pre-school bathrooms for fear that children might suddenly start drinking it. Now kids must come out and ask an adult to squirt some soap in their hands.

(B) Unaccompanied children under age 12 were banned from the Boulder, CO, library, lest they encounter “hazards such as stairs, elevators, doors, furniture…and other library patrons.”

(C)The Consumer Product Safety Commission announced a recall of certain fleece hoodies sold at Target because of lead paint on the zipper, which presumably could raise blood lead levels if the zippers are eaten.

(E) A New Canaan, CT, mom was charged with “risk of injury to a minor,” for letting her 13-year-old babysit the three younger children at home for an hour while the mom went to church.

(F) A Tennessee mother was thrown in jail for letting her kids, aged 8 and 5, go to the park without her, a block and half away from home.
