So now here is the solution
Sorry folks, there is no easy solution to this one! The best course of action is PREVENTION.
This takes the form of counseling young parents to be aware of the existence and consequences of restricted language.
This is not to say that there is not a place for restricted language. The child's safety and the parent's sanity sometimes demand it. What the parent needs to consider, however, is insuring EQUAL TIME for formal language.
This means they must take care to include ample formal language experiences each day.
For example they must follow restricted discourse with a formal explanation, after the need has passed.
I might say, "Edward-out of the Street-NOW!" and then follow it later with an explanation. "Edward, I yelled at you because you were in danger. The drivers of cars cannot see you and may actually hit you etc. etc."
