So my daughter is 6mo. Through a course of unfortunate events and sickness she has ended up sleeping in an inclined sleeper (yes I know not safe) this is literally the ONLY way she will sleep. We have been trying for over 3 months to get her flat in her crib. She used to sleep in her crib but after we stopped her swaddle she quit and got sick and had to be inclined. So we have tried multiple sleep sacks , varying degrees of tired , varying degrees of awake, noise machine with variety of noises, box fan, no noise, complete dark, low light, stomach, back (she rolls herself these ways) humidifier bc if she does doze off it's on her stomach and her nose stops up instantly. So here we are I am at a complete loss. Weve tried some cry it out like ferber type where we go in after just a min or two and she only gets more and more hysterical.
