Hi - I think you meant to reply to me regarding quiet time.
Quiet time isn't only for him, but for us too. It gets him into a relaxed state of mind. He can play with toys, watch his tablet, play on his Switch or read. It's his own free time to just chill out.
The reason we give him chill out time is because he's autistic and so am I. Giving him the space he needs to just do what he wants (within reason, obviously) means that he doesn't get overstimulated, and it gives me the room I need to calm down if I've had a chaotic day.
Honestly it really is beneficial to our family. And I understand 6pm sounds early but honestly it's the perfect amount of time for us ☺️
