Screaming uncontrollably - try to find the 'trigger' and work on
eliminating the cause, rather than trying to force the child to
stop screaming.
e.g. Incessant noise, hitting, disruptive behaviour whilst you are
on the telephone, making your conversation impossible.
In this case, the trigger was the telephone ringing.
How the problem was solved
(1) Behaviour book1.
(2) Praise for however long the child was quiet.
(3) Step-by-step visual guide for the child to follow.
(4) Reward (immediate) e.g. smiley face in behaviour book or taken
to shop for sweets.
(5) Praise the child for each uninterrupted phone call.
{6} Removal of one of the telephones, the one which had the loudest
ring.
Inappropriate behaviour whilst shopping
e.g. Screaming incessantly, demanding things, throwing themself
on the floor.
How the problem was solved
Once the behaviour book is established the child has some clue
how much you appreciate his good behaviour. Find out what he would
like to do, e.g. go visit a pet shop. Tell him calmly but firmly
that you have to get your groceries first then as soon as you have
them, you will go to the pet shop if he behaves in the supermarket.
