I wish that someone had written this down in letters ten foot tall or had shouted it at 100 decibles in my ear. (I probably still wouldn't have 'heard'.
We have just put our 6 month old (breastfed) daughter in her own room and, after months of constant waking, crying, wanting feeding, only falling asleep if fed, controlled crying, not picking up, screaming night after night after night and GUILT, GUILT, GUILT - put in her own room, she finally slept through. The first night she woke at 3, cried for a few minutes and then slept till 6.30. The second night she woke at 4, grizzled for a minute or two, slept till 7. Now she sleeps through, 7 - 7.
I only wish I'd done it earlier. Though I do miss her in our room, I know we were keeping her awake as much as she was doing it to us.
Now I have to learn to sleep through too.
