He was found by search patrols shortly after 1 a.m. Monday night - more than twelve hours after he first disappeared.
"We want to thank everyone, we are so relieved," the boy's grandmother tells Expressen.
The boy disappeared from a home where he had been with relatives. It is still unclear where he was found.
"I don't have any further details; it just happened," RLC commander Andreas Schäufele told TT at 1:30 a.m.
A massive search operation with dogs, drones and a helicopter has been underway for the boy, who will soon be three years old. All properties in the immediate area were searched in the operation, which also involved the Armed Forces, Missing People, mountain rescuers and the emergency services.
The police do not want to comment on whether there is any suspicion of a crime, but earlier on Sunday there was none.
