I had only vague suspicions that autism might be part of me when I started doing it a decade ago - I didn't call it unmasking because I didn't know what masking was.
I stopped scolding myself at home when I did weird or childish things. I gave myself permission to play with my dogs any way I and they wanted. I gave myself permission to make strange noises back to my parrot. My dogs love it, my parrot loves it, and I love it, because home is where I can be me.
