Children who have suffered damage to their spinal cords can sometimes also have reduced fine motor ability or general motor ability, as well as reduced perception. That is why you need to adapt the environment and CIC equipment to your child's conditions.
It is important to sit steadily and securely. Your child's hands should be free so that it can assist in the CIC procedure. You must always allow enough time to complete the procedure, so that time-pressure will not force your child to give up. The routine should be clear to the child, as well as his/her delegated task.
Remember that also Mum and Dad should be able to work in a comfortable position!
With the long-term goal of your child being able to go to the toilet and empty his/her bladder completely by himself/herself using CIC, there are of course several other steps. Like practicing getting dressed/undressed. By practicing these different steps, it gets better and better.
