I've been doing a lot of reading due to DS's ongoing sleep issues. And I get the premise that how they go to sleep initially in the evening is how they expect to be put back to sleep if they wake up...but it doesn't seem to work for DS!

A few nights this week, I've had amazing success with getting him happy and sleepy, putting him in his sleeping bag, saying night night, in your cot you go and lying him down. I then sit on a chair next to the cot and close my eyes, and he's put himself to sleep happily. But he then wakes up later in the night (repeatedly) and nothing expect a boob will get him back to sleep, can't just put the music on or give him a cuddle to calm him down and then pop him in the cot, pat/ssh doesn't work, nothing works!
So if he's going to sleep in his cot with just my being there, why isn't it working later in the night? What am I doing wrong! I am completly at the end of my tether as DH will try to settle him, but after 15mins, he comes to get me. And I'm just plain exhausted!
