Sleeping in crib

Hello I’ve been wanting to get my son to sleep in his crib lately since I do co sleep with him and I just wanted some advise on what methods worked for y’all here’s some background of him. he is currently 9 months and breastfeeds he has never been able to sleep through the night before he usually wakes up crying 2 or 3 times a night and 9 times out of 10 won’t fall back asleep unless I breast feed him and his crib is currently having to be in our room. Thank you.
