Pacifier

Hey mommas, My 17 month old only uses a pacifier for bed/nap time but is soooooo reliant on it to sleep. He sleeps amazing (13 hours throughout night, 3 hour straight nap during the day) but needs his pacifier to do it. Has anyone weaned their kids off of a pacifier who is super reliant on it?! I need advice/tips to start the weaning process because i feel so lost! TIA
