We used controlled crying to help our daughter get to sleep easier at 6 months. This was hard work at the time but now, at 10 months, we can reliably put her down at the end of her bed time routine and she happily drifts off to sleep.
However if she wakes up in the middle of the night, it's a different matter. Controlled crying doesn't seem to have effect there.
We seem to go through phases of good nights, where she'll sleep through, and then bad nights, where she'll wake up between midnight and 3am and then be away for three hours. If we do controlled crying, she spends this three hours crying, and at times really working herself up. She won't stop crying when you enter the room.
We've recently lost patience and started trying anything else to get her to sleep. Picking her up instantly stops her crying but she just gets excited and happy. I have had limited success rocking her to sleep, but it takes a long time. One time we even let her play with her toys to see if it would tire her out, but she just played for three hours.
So we need to know either what we can do to make controlled crying have the effectiveness at night time that it has at bed time, or alternatives for getting her back to sleep. Preferably ones that don't involve a lot of crying or are quick!
I should add that although she's 10 months old, she hasn't got any teeth yet. These good night/bad night phases haven't coincided with any teeth so I'm not sure they're teething pains.
