What would make the most difference to your health and wellbeing (physical, mental, and emotional)? Start with that. For me, it was being able to put her down in her cot for a couple of hours at bedtime so I could have something of an evening. We set up her cot sidecar style to our bed so I could easily nurse and settle her in there, and then go downstairs. I was okay with bringing her back into bed with me at some point during the night, and there were some tricky nights when I went to bed a bit early because she kept waking up. It did also mean she knew (and knows) that my bed was still an option.
With her, that seemed to be okay – she still quickly learnt to settle in her cot for the first part of the night, and it does mean that we've never worried about setting up 'bad habits' when she's ill/teething/etc. the way some people (and sleep training approaches) seem to. If a cold is waking her up lots of times a night, she comes in with me, the cold passes, and she seems to accept the return to normal routine with no fuss. I'd like to think it's because she knows the option is there if she needs it, but who knows what she's actually thinking. Of course, a different child might decide that if the option is there, they want it all night, every night, and you might not be able to be so flexible.
Putting her in her own room may well help if you have that option. We couldn't, and I'm certain some of the wake-ups around my bedtime were very much about knowing I was there (or should be) and since I was, she wanted cuddles! If it isn't an option for you, or you don't want to, it certainly isn't essential to see progress – we managed.
