We have finally bitten the bullet and taken on a cleaner. We (the cleaner and I) agreed in principle that some jobs would be done each week and others just from time to time. Would it be reasonable to prepare a list each week and ask her to work through the list and do whatever she can manage in 3 hours (and explain that it's fine if she doesn't complete the list as anything she doesn't do this week goes to the top of the list for the following week)? Grateful for any help / advice how to approach this.
