Oh poor you, SB. I remember this so well. I have never been a good sleeper so having children tipped me over the edge at the best of times. What eventually helped me was just to stop worrying about not sleeping (this took me quite a number of years to develop and slipped back after No. 2). I still wake about 8-10 times a night (only one or two of those induced by the children, at least one induced by the birds outside my window or planes). I used to use a mantra (meditation), I also used to design my "dream house in my dream location" but I never, ever thought about 'not sleeping'. I am now able to wake up and drift off relatively easily, even when a fidgety 4 yr old climbs into bed around 5am. Keep strong.
