Suggestion #23: If the child is showing sign of being upset, allow them time to calm down.Autistic children may become over stimulated and overwhelmed. Essentially, their mind needs time to process and they may need more time than you would think to process whatever it is that is upsetting them.
It will be so much easier for them to handle, if you slow down the stimulus as soon as you notice them becoming agitated. Asking them a lot of questions is not the way to lower their stimulus. Instead, try to remove them away from any loud noises and sensory input before they are at a breaking point.
