I went to trisillian which is a sleep school based in NSW. They also don't use 'control crying' they do however use "comfort crying" or 'comfort settling' I think they call it. If you google Karitane that is a basic outline of what they didn in Trisillian. It depends on what your definition of controlled crying is because
IMO this can be a form of controlled crying.
If there is anything else you want to know let me know.
