How do you get your baby to sleep?

To swaddle or not to swaddle? Nursing? Cry it out? Which approaches have you used and how do they work? Where did you get you advice from? Website? Family? Cultural tradition?
I'm doing a research about parenting around sleep at the University of Waikato. We'd like to hear your stories of successes and troubles!
This research is approved by the ethics committee and your identity will not be disclosed.
There's an online survey that'll take about 15-20 minutes. We'd also like to hear your stories in one-on-one interviews if you choose to.
Here's the link to the survey: http://psychology.waikato.ac.nz/babysleep.htm

Thank you so much for your time!!
