How can I teach my child to invite friends to play and to respond to invitations?

Inviting and responding are skills that stick when practiced in concrete situations. Break it into short steps such as "say 'let's play together' then wait for the reply," and show it with picture cards or a simple script. Practice at home by swapping roles with an adult, then move to real situations. For responding, starting with two choices—"sure" or "not now"—makes it easier to answer. At first, having the teacher help mediate and preparing a shared favorite activity raises the chance of success. Praise the moment it goes well, specifically.
