How often change order occurs? How big is the change order impact to overall schedule?
Yes I agree, we cannot change the baseline everytime. As I understand, baseline contains not only scope, schedule and cost, but also reflect the strategy how to manage the project execution.
Changing the baseline --> change of execution strategy
Based on my experience, if the change order has significant effect to the schedule (ex: shifting overall schedule completion/ key milestone, changing of sequence, changing execution plan, etc.), then re-baseline must be done, and progress plan will follow.
But if it has only small impact to the schedule, no need to do re-baseline, just add new activities to cover change order.
Schedule change history should be made and updated each time change happens in schedule, it will help tracking the schedule in later time.

you don't once you have the baseline YOU DO NOT MODIFY THE BASELINE. What you do is you copy the baseline and as the project progresees you PROGRESS THAT schedule this is the updated schedule. Thne can ADD any change orders to the updated schedule then you can compare it to the baseline so that you can see what was added and look for differences. If you add it to the baseline then you will NEVER see any differences.
