If you have only one kid, "sleep when the baby sleeps" works fine. Once you have two kids it is all over. I am fairly certain that I will never nap again. For the most part, my exhaustion is manageable. The really hard part is reading books in the late afternoon - it never fails to put me out. Poor Matilda says "wake up, Mommy" over and over as I attempt to make my way through a book. In only 38 short days Matilda will start preschool and then I will have 3 afternoons per week to nap with Porter if he happens to sleep during the short window of time that M is gone. It sounds like paradise to me. Of course I could always use that window to exercise too, but that's another hurdle.
