My dd is 8 months and she still requires me to lay down next to her and to nurse her to sleep. Sometimes she'll wake up right away, other times she'll sleep for an hour (but never longer than an hour before I have to comfort nurse her back to sleep).
I'm still a firm believer in the NCSS. I'm still working on the alternative soothing. It's a very slow process, but I've heard fantastic results. Just take baby steps and don't pressure yourself.
I know it's really hard right now.... but I promise... it will pass. Just try your best to take care of yourself in the meantime.
