A young boy with autism named Tupper suffered from nightmares so severe that he could only sleep for 20-45 minutes at a time. He also had problems with controlling his emotions, and would often bang his head on the walls and floor of his house. The day he met Lego, the dog, however, everything changed.
Lego started by laying his head on Tupper, and within minutes the boy was able to fall asleep - and stay sleeping through the whole night! Lego even knows how to calm Tupper down by placing his paw on him whenever he's getting too stressed.
