Please help! About to resort to letting my daughter cry it out.. dunno what else to do...?

me and my husband went through almost the same thing with our 5 month old daughter. it was finally the doctor that told us to try the CIO method. what we would do is lay her down in her crib awake and give her the paci, then we would kiss her goodnight, i would sing to her and then leave the room. at first she would cry as soon as i left the room, but i would not go back in for 5 minutes. when i went in, i gave her the paci patted her belly, told her i loved her and left again. i kept this up until she went to sleep (surprisingly, the first night, it only took about 15 minutes). then when she woke up in the middle of the night, i would wait 5-10 minutes (whatever i could stand) and do the same thing, go in, give her the paci, pat her belly, and leave the room. she only got up once that first night!! i could not believe it worked so well. for about 2 weeks she would still get up once a night (when it used to be 5 or 6 times) and would go right back to sleep. then she started waking up and crying for about a minute and putting herself back to sleep. she is now at the point to where i put her down at night and she does not wake again until the next morning! absolute bliss!! i hope this has helped you. i also was very torn about letting her cry and there were times that i would think i couldn't do it, but i persevered and my daughter is a happier baby for it!
