My little guy has gone through phases like that. From day 1 I have nursed him to sleep, but around the same age your LO is he needed to be "bounced" (basically over one of our shoulders while we sat on the edge of the bed and slightly bounced). I think it lasted a few weeks and we've been back to rocking and nursing. We put his crib in our room and he goes down for the first few hours then comes to bed with us after his 1st night feeding.
