L.M.
Keep being the squeaky wheel Grandma! Keep calling and being an advocate for those children. Call to report, call to check on the status, every other day if you need to. Call to give them the witnesses names again. If you make enough noise, your case will be moved to the front of the line so they don't have to hear from you anymore.
And, yes, a child passing out requires an immediate call to the doctor and they will most likely advise a trip to the ER.
