Sceduled/ consistant “bedtime”

I keep seeing posts about babies’ “bedtimes” at night. Is any one else’s baby all over the place? I have no schedule at all and I can’t imagine implementing one because baby calls the shots! I put him in his basinet when he falls asleep between 8 and 10 and oftentimes he’s up a half hour later and I can’t get him back to sleep without starting the whole process of feeding/burping/changing/rocking all over again. So then he’s up until like 11/12:00. I don’t know how to get him to do a long stretch of sleep and not think it’s a nap! I’ve got the dark room, white noise, swaddle. I’m afraid we’ll never have a decent bed time or schedule! 😩 Any mamas in the same boat or am I the only one!?
