I don't know who is giving you this parenting advise but they are way far off the mark. If riding a school bus was neglectful the school would not provide this service now would they??
If you want the definition of child abuse/neglect go to the child welfare information gateway at www.childwelfare.gov also go your state code of law and look for the chapter on child welfare there things are difined more clearly.
What you have here is somebody's opinion, somebody who doesn't know what they are talking about. Stop being gullable.
