I honestly thought that DD would be the same. I used to feed to sleep, but when that stopped working I went to rocking to sleep. That did the trick for months but then also stopped working (they always change it just when you think you've got it nailed :)). So I started looking into different methods as I know that, while it has its place, controlled crying wasn't for me. So I looked at no-cry sleep solution, baby whisperer PUPD and Andrea Grace. I did a bit of a combination of them to find what worked for DD. I apologise in advance if it turns into a novel, but this is what we did:
I started off by getting a solid bed time routine sorted. After dinner DD has a bath, then into her room to get dressed for bed, has a feed, story, song and then lights out. I have music turned on low and a very dim night light. I then put her down and say "I love you, night night, it's time for sleep", turn on this star on the 5 minute setting and give her that time to crawl around in her cot. When it turns off I place her down, repeat the phrase above and keep my hands on her. I make sure that I'm not making eye contact with her. If she tries to sit up or stand, let her, then place her back down and repeat. I keep doing it until she stays down. I believe the most times I did it was 92 in a row. It is a bit of a killer on the back to stay bent over the cot, but does pay off. If she gets a little upset I talk to her in low tones and reassure her that I am still there and it's time to go to sleep, keeping my hands on her. I stayed in the room for at least 10 minutes after she had gone to sleep.
I started off for the night time sleep and just kept going until she went to sleep. The first night I think it took about 30 minutes. I started it for naps the following day. I do it for naps in 40 minute increments, if it hasn't worked in the first 40, get him up for quiet play for 10-15 minutes. Then repeat for another 40 minutes. If it doesn't work in the next 40, get him up and carry on with your days as though he has had a nap. Then bring the next nap forward a little to compensate. This has only happened to me once.
I did the above for three nights and three day times and moved to the next step. That for me involved doing the above with the routine, the phrase, but after I lay her down, I removed my hands but stayed standing next to the cot. Then when she sat/stood I placed her down again. And again and again! It will take a bit to get used to, again I started it with the night time sleep as you don't have to stop after 40 mins. Then repeated the next day for naps. I did this also for three nights and three days.
Next step was to do the same with the routine, then place her down and repeat the phrase. I then sat down next to the cot. When she inevitably got up again I would place her back down and sit back down myself. I would only place her down the first 5 times. Then I would say to her "Lie Down. Sleep.". In my very best firm mummy voice. I would do this a few times and if she hadn't lain back down, would get up and place her back down. Again, repeating until she went to sleep. Did this also for three nights and three days.
Next was to follow the routine, lay her down, say the phrase and sit next to the cot. I would not place her down again, but instead would just say "Lie Down. Sleep". Each time she got up. Again, three nights and three days.
Where I am up to at the moment is I put her in her cot, say the initial phrase, turn on the star, sit in a chair in the room and wait for the star to stop. Once stopped I do the "Lie Down. Sleep." until she does.
I plan on moving on tomorrow night to sitting in the chair whilst the star is on and then pottering in and out of the room as she tries to settle to sleep, doing the "Lie Down. Sleep." as necessary.
The key for me was that I was never leaving her to be upset on her own, I couldn't have handled it. There were a couple of very minor protest cries at the start, but that's all they were. She hasn't had any really upset/distraught crying. If she did I would pick her up until calm and then place her back down.
Hopefully not jinxing myself here, but she self-settles beautifully at night now where she could not before. I think that it was recognising that she was still in her cot where she went to sleep and it was ok to go back to sleep. You also would need to repeat in the middle of the night for any night wakings.
I hope that this can be of some help to you :). I never thought that DD would respond to it, but needed to do something as we couldn't continue the way we were. So far I have been really happy with it and have made fairly quick and hugely noticeable progress.
I again apologise for how long that turned out to be 
, and please let me know if there is anything that doesn't make sense.
