We went to visit my Parents in law who live about twenty minutes away. On the way home in the car he tried to open the door and undo his seat belt on a busy open road. The child locks were on, we pulled over and put his seatbelt back on. He seems to have meltdowns over the last couple of days if he can’t just run where he wants. During lockdown he’d have meltdowns if he couldn’t run down the street but these seemed to have stopped. I don’t know if anyone has any ideas how to stop this behaviour. My Son has Speech and Language delay and is awaiting an ASD assesment.
