Yeah I've started doing that, i'll pop her down in her cot and potter about go to the bathroom etc to see if she will settle on her own, mostly she starts to cry after a time so I pick her up and settle her in arms, or pat bottom or do dummy.

She seems to re settle herself fine if she wakes over night unless she needs something like food, or nappy or whatever, just the initial going to sleep is the bit she needs to work on so I'm not going to force the issue.
