I used to babysit off the books with one 12 years old he was very protective of me so he didn't like anyone near me so I would have to tell him we can be friends and try to show him it's ok to talk about how he feels. I also was a part- time nanny for another 4-year-old I wasn't aware of his situation till he had a moment and all I did was ask are you hungry? Do you want to see tv ? Anything that would make him happy and calm I did tell mom and that's when I found out he was autistic. I had a toddler in a classroom had a seizure I called the emergency line had teachers watch him comforted him and made sure his parents was aware as well.
