        Kathy started at my nursery school at the age of three. She settled into the group easily, and would

be first on the slide and highest up the climbing frame. She could put on her coat withouthelp and not only

fasten her own buttons but other children's too.    

       She was a lovely child but unfortunately a scratcher. If anyone upset her or stood in her way,her right hand would flash out fast and scratch down the face of her playmates. Children twice her age would fly in

fear from her.    

      This must have been very rewarding for Kathy but obviously it had to be stopped. All the usual ways

failed and then I remembered an account by G Atkinson of Highfield School,of how fights in the playgroud had been stopped. No punishment had been given, but the attacker had been ignored and the victims

rewarded. So I decided to try this out on Kathy.    

      With a pocketful of Smarties I followed Kathy around. She was so quick that it was impossible to

prevent her scratching, but I was determined to stay within arm's length all afternoon. All was peaceful but

then I saw Kathy's hand moved and heard the scream. Gently I gathered up the little hurt one in my arms

and said" Nice , nice  sweetie" and  I  put a  Smartie  into  her mouth. Kathy opened her mouth, expecting a Smartie and then looked puzzled when she got nothing.     Soon came another scream , this  time from

John. While  holding him in my arms , I  said , " Look , Kathy , a nice  Smartie for John" and put it into

John's mouth.    

      A smile of understanding flashed across Kathy's face. Minutes later,she came to me and said loudly,

" Give me a Smartie!  I have hurt my finger ! "     " No , " I  replied , " you'll  get it  if someone  hurts you." 

     On purpose, she turned and scratched a nearby boy, Tom, and waited quietly while I mothered and

rewarded him , then she walked away.She has never scratched a child since.    

Parents who find older children bullying younger brothers and sisters might do well to replace shouting and punishment by rewarding and giving more attention to the injured ones. It's certainly much easier and more effective.
