Other things you can try, is the shh pat, method and if she likes going to sleep on you is to put her down before she actually goes off completely, this may wake her up slightly and then you can pat shh in the cot.
I have to say we are trying it differently we have had to break a reliance on feeding to sleep first and so now we pat shh baby to sleep on us, this consistently works now, and so we are now moving to putting her down as she nods off..
Be aware it may cause other issues at first such as her not sleeping as long (maybe hitting the 45 minute barrier)
