or i did have, she was getting sleepy, you know when their eyes go glassy, so i took her out, swaddled her and put her and her 'snuggly' comforter into the pram and she is now asleep, the trick with her seems to be catching her at the right moment of sleepiness, so she is awake enough to know she is being put down, but that she can see that i am nearby (and hear me i tend to hum to her) andthen she will go off, sometimes with, sometimes without the dummy.
other times not at all and i stick her in a moby wrap and walk about, i think that in the first 4mths sleep is such a constantly changing variable, ie the amount of it they need and what you have to do to get them to sleep. the main thing is to find the easiest thing to do, imo thats what works with least fuss fromthe baby :)
once they get older say 3mths i think you can start trying to establish more of a wind down bedtime routine, but really up till then i would just go with it and make sure you rest as much as you can (hard i know with other children)
but my ds4 is currently napping, the baby is now asleep and dp has taken the elder three to the park, so i am going to follow my own advice and have a little sleep (have a chest infection) 
btw i understand your worries about nto wanting baby to suck to sleep all the time, my first three would only ever sleep at the breast and it was exhausting but they do grow out of it, maybe with a little help along with way, but i dont think you need worry about it at such a young age :)
