This happened with my first and it was around 14 weeks when he suddenly switched to a 7 pm bed time.

I reinforced night/day from the very beginning so she would learn the difference, even when we were going in every 2-3h. I put her down in her bassinet around 8pm, turned the lights off and sang her a song. Then I would watch with a monitor and go back in (but kinda slow-walk in case it was just loud grunting) if she woke up, but then leave after feeding/diapering, until our own bedtime (bassinet was in our bedroom).

I was in the same boat with my 4th and ended up getting the snoo. Best baby purchase ever. Inwas seriously losing my mind and after a week she was the best sleeper.

This is my third baby but I don’t remember having this issue with my first two. My 11 week old regularly won’t go to bed in her bassinet until 11 or 12. I want to pull my hair out. I know it takes some time for their bedtime to move up, but this is later than I’ve dealt with in the past. Any tips to move it earlier faster? My most determined efforts just leave me frustrated spending hours on bedtime. I’m tired.
