Self soothing and sleep training

My little one is 5 months and he goes to bed really easily, normally he’s out after 30 seconds. Naps take a bit more work but are generally easy too. My question is night wakings. I dream feed him and he only wakes up to feed once but wakes up 1-3 times and cannot fall back asleep unless I put his pacifier back and sooth him a little bit in some way. I’m not sure how to wean him off the paci or help him/teach him how to fall asleep again during those wakings, specially since he falls asleep on his own perfectly at bedtime. What has worked for you and what are your experiences? Thank you!
