Children with CdCS may have behavioural problems, including hyperactivity, aggressive and oppositional behaviour as well as sleep problems.
The first thing to do is to keep a record of what’s happening in the form of a diary.
To do this systematically, it helps to have 4 columns entitled “what happened”, “what led up to it”; “what happened as a result” and, usually most importantly “what response to the behaviour did I make”. Surprisingly, by doing this you may easily detect what is happening, and by altering your response to the particular behaviour, either stop it or change it for the better.
Clear communication that is concise and said with conviction using words or symbols that the child readily understands can help, as can focussing on good behaviour with lots of praise.
You can actively encourage children to do praiseworthy things such as tidying up their toys, playing nicely with their siblings or friends, etc. An ounce of praise is worth a ton of punishment in these circumstances.
Special Needs Teachers, Health Visitors and Child Psychologists are also good sources of sensible advice for families with children with challenging behaviour.
Lots of information is also available from the Challenging Behaviour Foundation.
NICE have also produced some guidelines for care of those with challenging behaviour which you can read online, as well as in an easy to read version.
