If your child is rigid and insistent on routine, your goal is not to get rid of this trait, but instead increase his flexibility. No matter how structured and routine you set up your household and your child’s life, changes will certainly happen. Because of this, there is no need to purposely create disruptions in the routine in order to expose your child to change. You will be faced with helping your child cope with both predictable and unpredictable changes.
Predictable changes will be easier to help your child adjust to. Upcoming doctor’s appointments, visits to relatives, a parent being out of town, and similar events can be verbally told to your child at the same time you and he post it on his wall. Ask him if he has any questions and ask him what he thinks would make the change go easier for him.
Unpredictable changes are harder not only for your child to cope with but for you to try to help him. The first goal is to offer him empathy for his upset and try to soothe him and calm him down. Later you can talk with him about why the change was upsetting and how he thinks he can feel less upset next time.
