Hi,
I have tried 'The no cry sleep solution' by Elizabeth Pantley. You can buy it from the Geobaby website. It's brilliant. There are lots of excellent suggestions for getting your child to stay asleep. It's not a quick fix solution, though as the author explains they don't really exist. Elizabeth Pantley has four children of her own, so her suggestions are common sense and tried and tested on her own children. You can develop a sleep plan to tailor to the needs of your own child, without letting them cry. I found her down to earth approach very reassuring. Good luck anf sleep will come soon.
