Has anyone heard of "Friendly Opposition?" One person who visited my centre, said One of my children has/is/uses Friendly Opposition. He does listen, does understand, but seems like he doesn't want to do what is asked. Ex. Tidy up toys, put snack bag away, etc. He does not hit, he only sits down or lays down, looks away...sometimes takes a lot of persuasion for him to do what is asked.
