I've just had interesting advice from Millpond with regard to getting the crucial and long-lasting lunchtime nap to extend beyond 30-40 minutes, ie one sleep cycle. She suggested trying to put bubs down as near as possible to the same time every day (within half an hour or so), and then if he wakes after one sleep cycle and won't resettle with gentle persuasion, I should get him up but then try to resettle him 40 minutes later for another sleep cycle (or not more than an hour - as if!). She said it could take 2 or 3 weeks of doing it every day, every day, but will eventually help him to get used to sleeping longer at lunchtime. And no leaving to cry - yay. I guess I'll report back in 3 weeks! The other thing I thought I'd try is picking him up just as he wakes and immediately take him for a walk, in the hope that he'll sleep. Sort of an adaptation of Pickle's method.
