Social stories are a good way to help children understand what is going to happen or what is expected of them in different situations. If a child is feeling anxious about returning to school (Which is completely normal and understandable given recent circumstances.) reading a social story regularly prior to return will help them to process the idea that they will be coming back to school.
With the recent lockdown some children may be feeling anxious about leaving the house. This social story is to help understand that feeling worried is ok, but also that it is ok for us to go outside of our houses again.
