HI, I HAVE A GRANDSON WHO IS 6. FOR THE PAST 3 YEARS HE SHOWS SYMPTOMS OF OCD. BUT LATELY HE IS ACTING OUT YELLING KICKING ETC. LAST YEAR HE FOUND PORNOGRAPHY ON THE INTERNET. HE HACKED HIS NEW CHILD TABLET (WHICH SAID A CHILD WOULD NEVER BE ABLE TO FIND PORN) BUT HE DID. ONE NIGHT ABOUT 2 AM MY DAUGHTER FOUND HIM USING THEIR FAMILY COMPUTER LOOKING UP PORN. ANY SUGGESTIONS AS TO WHAT THEY SHOULD SEEK OUT FOR HELP OR ANY DIAGNOSIS?
