What is the age where children have the easiest time when their parents divorce?

First of all, this is not about me. I have had troubles in my marriage, but we are not looking at divorce right now.

My therapist suggested that she thought the best time was when kids were sophomores or juniors in high school or college. A lot of people wait until a child has just graduated high school to do it, but she said that was very damaging, because they are in transition from one stage of life to another. That’s hard enough without the parents divorcing. So, senior and freshman years are bad.

What are the considerations that you think are important when considering when to divorce (with or without kids)? What age should children be in order for them to have the least hard time dealing with their parents separation? If you are a child of divorced parents, how old were you when it happened, and how did it affect you? Do you think it would have been any easier if you were a different age?
