Did you hire a sleep consultant? What did they have you do that was different?

Basically did you end up doing something different than the traditional methods (PUPD, Ferber, CIO etc.) that worked for you? We've been trying since LO was 5 mo, tried all 3 of the above methods but she still cries (sometimes screams) for 10ish minutes every night before falling asleep. 9 mo now. I worry that I'm damaging her. Was wondering if hiring a consultant would be different. Not nap trained.
