I guess it would be better for the child to have visitation rights for ten years rather than a week to see a critically ill parent. I don't know if we could include a definition of timeline. In the best scenario, somebody who was classed as being critically ill would recover at some point through some new medication or treatment. But I'm not going to argue about a timeframe. I don't know how you'd administer that. If it's a doctor's decision or observation that this person is terminally ill, and he states that, then I think that's the criterion the judge would have to go on.
