I'm not sure about any tricks but we have been sleeping DS in his crib since about 5 wks old (he's 12 wks old now). In fact, he rarely wants to sleep anywhere else, which is also a pain sometimes.

I guess you can just try putting her in there once you have rocked her to sleep.

Also, we sleep DS on his tummy (although I know it is a controversial topic) and he seems to do just fine.
