Leaving the house can involve several difficult transitions at once for an autistic child: stopping an activity, getting dressed, gathering belongings, and going somewhere that may feel unpredictable. Explain the plan ahead of time, give warnings before leaving, and use a simple visual sequence such as shoes → jacket → backpack → leave. Letting the child bring a familiar comfort item can also help. Keeping the leaving routine predictable can reduce stress and make outings easier over time.
