Allie Pallie wasn't describing controlled crying.
Anyway, at this age my DS would only sleep in a wrap carrier, or me bouncy on a Pilates ball. But wasn't feasible at night so we had to get him to fall asleep in the crib. I also felt that he was getting annoyed at me. He would cry a bit and would have to pick him up to calm down and I realised he actually needed to cry for a couple of minutes. I couldn't tell his different cries at the time so I needed to let him go for a minute to see if he was just trying to get himself to sleep.
Lots of patting and shushing was involved. I also use white noise. I use an app on my iPad.
A good wind down routine is good too. Back then we would wrap in a double swaddle, close the blinds, sing a lullaby while watching a night light then put him down.
It does take time as they learn that when you do this routine it is sleep time. I did it before every nap and for bedtime.
