Pacifier problems

Y
Ladies, your advice, how do I get my little 5 month old out of the pacifier zone? I can't sleep at night because it falls out and she wines for me to put it it back on. This goes on once every hour from midnight til about 3am-- then wakes up at her usual at 5-530am for her first formula milk. I am just exhausteddddd... She also naps sometimes without it but if it's not in her mouth she won't nap more than 40mins... Helpppppp!! 😩😩😐
