its when you lay your baby down in the cot or crib with very dim lights talking softly. you lay them down pat their tummy for a short time and move away from beside them, it takes alot not to lift your baby but babies get to know if they cry they will get picked up, dont get me wrong i held my babies alll the time but when it came to sleep time they were taught to fall asleep by themselves. they need to be able to fall asleep without rocking cos its good for them but for you too, anywaywhen you've moved away you could stay in teh room at first just near the cot and pat their tummy briefly when they cry to settle them, keep diong this, moving firther away each time they settle without being lifted, if your lucky enough and stick to it you could have lovely evening wher you can lay your baby down in bed at night after a cuddle and a kiss and leave the room while they are still awake, i was able to after 2 nights i think with mine.
