What can i do to get my 5 month old to fall asleep on his own?

he's 5 months and basically to get him to fall asleep i need to cradle him in my arms and bounce up and down on the bed and he's asleep sometimes it takes minutes some times longer and sometimes i'm just so tired myself, he wakes every 2 hours for feedings too!!!!! and now with the hour change i;m dreading what;s to come!!
