Hi Yinzer, I feel for you... that's been the case with our son off and on too.
At that age, we used to just bring him into bed with us when he woke up at night. Not ideal, as then our sleep would be restless, but better than having to get up 2-3 times in the night.
A few times we tried the cry-it-out method and hated it... it never got easy. I agree with Andy that it's not really a great idea... I always felt that not responding to my son's cries would be damaging in that he would unlearn that he could communicate his needs. Better than that was to go in and put our hand on his back, and either sing softly, or just gently rub his back.
I've heard some people suggest doing that, but then slowly getting further and further back, so the baby knows you are there and is comforted, but you can get to the point of being outside the room and being able to comfort your baby by just letting him know you're there. We never tried that; never had the patience for it.
What we do now when he wakes up is my husband brings in a pillow and blanket and sleeps on the floor of his room. I'm sure this will change as soon as he's out of a crib and in a toddler bed.
Anyway, whatever you do, your son is still going to be a happy baby, and he won't grow up to be a serial killer. You're a loving, conscious mother, and that's more important than any of these parenting theories. You can't be a perfect parent - there's no such thing. You can just try your best, and if something isn't working, you learn from it and change. If you try any method and it doesn't feel right, you'll change your tack, because you're paying attention to your baby's response.
