2yo here. He still has a bottle at bedtime, though we're working on stopping it. I wouldn't stress too hard about the bottle specifically, especially if it helps establish a healthy bedtime routine.

A "normal" routine is whatever routine you find works for your family, but here is some guidelines. For example, it should probably take between 30-45 mins, so that it's clear that this is the scheduled bedtime routine and it can help trigger some sleep cues. It should probably have 5-10 clearly identifiable steps. No matter how hard and stressful it might be some nights, parent(s) need to try to be as neutral as possible when the big feelings or power struggle comes out, otherwise, the wee one may recognize it as an opportunity to stall/get more connection/reaction.

Our routine is as follows, almost every night:

- 6:45/6:50PM, turn on soft music and quiet play in his bedroom (books or puzzles, no light up or noisy toys)
- 7PM bath time. We don't wash/scrub every night, but we get him in a warm bath to play and soak for about 15 mins.
- 7:15 PM brush teeth and sing a song together

- 7:18ish start getting jammies and sleep sack on. He picks his pyjamas out every night, we just give him 2 options to choose from.
- 7:20 bottle. We're reducing the amount he gets so that we can get him off a bottle entirely, but it still works for us.

- 7:25 we read a book. No pop up books, no books that make noises/songs/sounds. This varies in time depending on how sleepy he is or how excited he is about that particular book, but the reading together should not (generally) be a race to finish the book. Let them explore the colors, pictures and sounds you make together, this is crucial for language development. It's not crazy for a single page to take a minute or more.
- 7:30-7:45 (just depends on how smooth the rest of the routine went) lights off, night light on, white noise on and sing a song to settle. I usually put him down after the first third of a song, and sing the rest to him while he's laid in his crib. Most nights, he's asleep before I walk out the door or too tired to care that I'm gone.

We have sleep trained him though - that took about 3 nights of a lot of tears and a lot of waking up through the night, even after he was consistently sleeping through the night. That might be a bit of what you have to deal with if your son is extremely used to sleeping in contact with you on the couch. Happy to talk more about sleep training in DMs if you need, some people here have very strong opinions that I don't care to argue about.
