TakingCaraBabies Toddler sleep class

Has anyone taken the TakingCaraBabies toddler sleep class? My 2.5 year still sleeps in his crib attached to our bed and has to fall asleep with skin to skin contact. It takes an hour to get him to sleep and we have tried no naps, more naps and even longer and shorter naps and nothing helps. I’m interested in the course but it is $200 so I wanted to hear from other real parents who have taken the course. Did it work for you?
