There was a thread about this recently in AIBU and I seemed to be a bit different to other posters in that most didn't do sleep routines until much later, whereas I've done them with both of mine from day one and have never had a problem with reverse cycling, although I do entirely acknowledge that that could be good luck and not good management. My first was a very, very frequent waker, so don't assume it will lead to blissful full nights, but he had definite night sleeping patterns where he was much easier to get back to sleep at night than in the day just didn't bloody stay that way from early on and he didn't often stay awake for long periods at night. My second, currently, nine weeks old, has had distinct appropriate night sleep versus daytime sleep since he was a couple of weeks old. Just in case it is my utterly exceptional parenting that has influenced this 
here is what I did/do with both,but more so with DS2:
- 7pm bath, preceded by as much feeding of DS2 as I can or that he asks for if he's in a cluster-feeding mood (I'm EBF as well)
- Pyjamas, into our bedroom where he has a co-sleeper cot, swaddled, white noise on, lights off - I keep the light on my phone on so I can see that he's not falling asleep on the boob, but I keep it well out of the way and out of his eyes.
- When he's had enough of a feed and/or is looking very sleepy, he goes into his cot, phone light goes off.
- He goes to sleep with me lying in the bed so he can see and smell me. I'm gradually moving over the side of the bed away from him so that he gets more and more used to falling asleep without me nearby.
- All night wakings are done in complete darkness. I wake up as soon as he starts wriggling around and smacking his mouth for a feed. I take him out of the cot and re-do his swaddle. Sometimes this is actually enough to put him back to sleep as he just wants to be nice and tightly wrapped again. Otherwise, it wakes him up a little more fully so he'll take a full feed, then back in the cot. The white noise runs continuously all night.
Getting to step 4 above took a little work in that I progressed him from full co-sleeping to his cot over the course of about four weeks, and it was about this same length of time that it took him to do a full night in his own cot (with wakings for feeds, obvs). Sometimes I would have to take him into the spare bedroom for a step back to (safe) co-sleeping but using some techniques from No Cry Sleep Solution (holding him in his cot until he fell asleep, picking him up for a cuddle at the slightest grizzle if he went in his cot, putting him down in side lying initially then gradually rolling him onto his back once asleep).
Main rule is once they're in the bedroom for the night, keep the lights out, and do not take them into another room once they're in there, especially not another room with lights/TV on.
During the day, get her out in the sun as much as possible, and feed her as much as you possibly can, so that daytime is about light and food, while night is dark and sleep. Also try to make sure that she's not awake longer than 45-60 minutes between naps during the day, or she'll get into over-tired zone which will, ironically make her stay awake longer, and make it more difficult for her to get to, and stay, asleep.
About to post this essay now. Here's where I find out 15 other people have posted in the meantime making all my advice look like a load of bollocks
