I think I've mentioned before, my dirty little secret, to getting it all done: Naps.
When I was young I couldn't sleep during the day without waking up with an awful headache. My mother, on the other hand, often nodded off in the chair on a Saturday afternoon. Now I've finally mastered it. And I seem to be able to do it whilst still keeping an ear out for the kids.
So there you have it. A couple of times a week I have a little power nap in the afternoon or sometimes just after the kids have had their dinner. Biggie usually says he'll give me ten minutes. It's the key to surviving on less than six hours sleep a night. That and Sunday sleep ins.
