Best Practice: Soft-Deleting Parent with Soft-Deleted Child Models

Hi - I've hit the "Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails" when attempting to soft-delete the parent of the soft-deleted child. I put this issue through Larry AI and the suggested alternatives are:

1. Remove the soft-delete property of the child models.
2. Remove the model linkage between parent/child and leave the child models intact when soft-deleting the parent model, effectively leaving 'live' models on the database but orphaned.
3. Hard delete everything. The model I'm working with has six child tables and the likelihood of the user mistakenly deleting or misunderstanding the impact of the deletion is probably 33%, so having soft-delete protection is important, but not mission-critical. I've put an 'Are you sure?" alert on the button so that there's an opportunity to cancel the action. My question: In your experience, What are the best practices for handling this? Thanks - Rick
