I think 1-2 times a night at that age is WONDERFUL too!
I know that's not what you wanted to hear though.
For me....I tried to get him to go back to sleep without nursing around that age but it wouldn't work. So then I waited a couple of months later and tried it again...still didn't work....waited a couple of more and then it worked around 20 months or so.
I very loosely did what Dr. Gordon recommends. I wouldn't let him cry though. He would fuss for a few seconds and I would hold him close (in bed) and sortof rock/jiggle him and go shhhh shhh shhhh go back to sleep nursy when it's light out. Something like that. Sometimes it worked and sometimes it didn't. After it worked a few times then it started working most times and then all the time and then pretty soon it wasn't necessary at all...he would just roll back over and go to sleep.
I think our energy is the big key here. If we are tense or upset then they really absorb that and it doesn't work well. If we are truly calm and ok with things then they usually are too
