Baby Sign Language - Discipline Your Baby
I have comment for the question of the month.
You must stress discipline, especially for a child who seems to have found a way around it.
Tell her very good signing, but the answer is no.
Just like with speaking children you praise them for the effort of the question, but sometimes the answer is no.
There can be no way around it. Saying no to a speaking child will not stop them from asking, I believe that a non-speaking child will be just as repetitive and insistent.
Most children will bond even closer with the parents who set and are consistent with boundaries. No is necessary.
