my lo is almost 3 months old and I would love if we could start getting her to sleep on own. I really don't want to let her just cry it out though. Usually to get her to sleep she has to be swaddled and then we bounce with her on exercise ball. Sometimes she will last in bassinet for a few hrs, and other times we have to give paci and rock after 15 min. Is there a no cry way to help her sooth self back to sleep at night?
