How can I get my 9 month old to sleep by himself?

I have coslept with him since he was born. I made the mistake that I would be so tired while feeding him at night that he would stay w me in my bed. So everytime I try to put him down to sleep in the crib. He cries and mostly gets up so I have to pick him up put him back to sleep in my chest, then get him back into the crib. But he wake up up to 4-5 times. I’m not complaining I just want to know what do I have to do to make him sleep in his crib all night. I’d hate to do the letting him cry it out because I never liked to do that. But please, I need all suggestions possible.
