Help 😩

Does anyone have any advice to get my almost 7 month old to take a pacifier?? I can’t stand him wanted to suck on my nipple all.morning.long. 😭 it hurts my back so much laying on my side for that long but if I don’t he cries and it’s still too early to get up for the day so i do it so we can both get a couple more hours of sleep. Please if there’s any advice you can give me on how to get him to take one it would be much appreciated!
