How to put baby to sleep without bottle

Br

I’m a single mom of a 7 month old and he’s goes to sleep by bottle. I’ve heard you shouldn’t put babies to sleep by bottle and probably good reason. But now it’s impossible to put him to sleep with him sucking on a bottle, he won’t take a pacifier, I haven’t found a lovely he likes to soothe him, rocking doesn’t work nothing seems to work and I want to break him of this habit and get comfortable being without so when I take the bottle away I won’t have a hard time putting him to sleep. If you have any sleeping methods please help a mama out
