Baby can’t fall asleep in crib 😖 10 months

My son has been sleeping in his own room and crib since he was about 6 months old and does pretty well, waking up only once or twice a night. The problem is that he can’t FALL asleep in the crib...I usually put him in the crib when he’s already asleep, after he falls asleep on me. Any advice for helping him fall asleep on his own? And a heads up about how long he’s going to cry for?
