They are enthusiastic enough about the work, but are taking all morning to be ready to start it. Literally. All morning. I have always had difficulty finding ways to hand over to Josiah and Tessa the responsibility for being ready to start work at our agreed start time. To make it their problem not mine if they are not ready. None of the “logical consequences” I've come up with are really all that logical, and all of them require me to police things more closely than the kids or I enjoy.
The kids would be happier I think if we didn't have a start time but just started work whenever they feel ready, which might be two or three o'clock in the afternoon. The problem with that is that my energy runs out by mid-afternoon. I find it very hard to be alert, focused, patient and observant at that time of day. Also our activities end up having to be hurried so that dinner can be cooked in time for Josiah to head out for the evening (he climbs three evenings a week and goes to Boys Brigade another evening).
A few ideas are coming to mind as I write this. I might institute a kitchen closing time half an hour before our “start time” in the morning, since a lot of why the children aren't ready is that they linger over breakfast. I know a few families who have a kitchen closing time in the evening to facilitate getting off to bed at a reasonable hour. Something similar in the morning might help us.
