J - very occasionally (like about 3 times in total) that has worked. (I did such a silly happy dance last time she did it!!!). Just sat by the cot and stroked her back and she eventually went to sleep. This was reassurance that she can do it... just most of the time doesn't want to or can't relax enough to get there. Usually if I put her in her cot she either just cries instantly, or crawls around, stands up... plays until she gets fed up and then cracks it.
