putting tired baby to sleep

There are times where it is easy to put my 2 month old boy to sleep, when I have caught the "right timing". There are times where we miss that window (e.g sleepy during feeding but got awaken from burping. Or got woken up in the middle of the nap or sleep). He is clearly wanting to continue to sleep yet even after I carry him in my arms, walk around the house, rock him and "shhh" him, he is still refusing to sleep. The alternate is a cranky, fussy baby. I'm wondering what do other mummies do under this circumstances to put your LO to sleep?
