Hi, I went cold turkey a couple of weeks ago. My ds had just turned 5 months at the time. It took about 3 days until he'd settle as easily as he had when wrapped, infact, a couple of times I fed him to help settle/relax him. He also did a few 40min naps again, but seems to be over those now.
BUT I noticed his once per night waking started happening at 1amish instead of 4am ish. So the last 2 nights I wrapped him agian. To my delight he slept thru from 7pm - 5.45am! He did murmur at 4am, but I left him and he went back to sleep. I tried to wrap tonight but he wouldn't let me, so I've left him unwrapped. I know he can sleep all night so if he wakes, it's because he's unwrapped. I also know he doesn't need the feed. It might just take a bit of resettling.
So anyway...... all I can say is be prepared for a few unsettled days, but yes, it does get better. Oh and no, ds doesnt have a pacifier.
