12 yr old difficult child with autism was raging and grandma (guardian) called 911. They took the difficult child to an pediatrician inpatient unit at local hospital. Now the hospital won't let the guardians (grandparents) visit or release the child. There may be a lot of details I don't know, but can a hospital hold a child against guardian wishes? They say they think he is a danger to himself because he keeps hitting himself (he's stressed, he hasn't seen family in days).
