What is it?
Establishing what is acceptable and unacceptable. (Sometimes the children may not understand fully why something is not acceptable. While this can be explained - finally we have to train them to "know" and follow this by default.
When do we use?
In situations that demand safety - material, physical, emotional.
eg;child climbing stairs- has to hold the railing for safety- child may not understand the reason, but still has to hold the railing for safety.
How do we use?
Through consistency - mostly with our mouths closed. This is the core of firmness - the moment we start giving a lecture - the whole effect of firmness goes away - the IMPACT is because we are MUM.
We also use Non-verbal signs
If at all we need to be verbal- we use a pre - established rhyme or chant about the issue - like " I Hold, I hold, I hold .. the railing .. whenever i am on stairs).
We may also point the child to a pre-fixed visual of what is acceptable.
But the real key and the essence of firmness is CONSISTANTTLY doing the same thing with MOUTH shut!
