When my son was younger, he was the same way. We used a visual schedule and PECS so he knew what to expect. If he wasn’t ready to do something, leave, eat, etc., I set a timer and give a verbal warning/cue. “In five minutes, we will clean up.” It helps to set a timer.

Thank you!

He needs time to digest events.
A 10 to 15 minutes break between events would benefit him.

Thank you for your feedback. I will definitely try this.
