DD is 12 weeks. Over Christmas, I made a real effort to move her to the next to me cot after co sleeping all through the newborn phase with sling or contact naps in the day. It was working!!! One morning nap and down at night from 9/9:30 with two feeds. I could even get her settled without picking her back up if she woke. I’d get her back in with me for the last stretch of the night but generally was very happy. Suddenly, she won’t stay down in the cot! 10 min in the day maybe (I do have blackout blinds coming) and maybe 30min at night. We have a consistent nap/bedtime routine - white noise etc. I know this is the dreaded regression and am ok with co sleeping until she’s rolling but I’m so paranoid about un doing all my good work. I’m going to keep putting her down to start, even if she ends up with me - but is that enough? Will she just naturally start self settling?
