Krainy - hello! Sounds like things are still working themselves out for you, but it's great that your DD is doing some later wakings, if not every morning! A diary is a good idea, I always do that when I am trying to work DS out.
Do you think your DD may be in the process of dropping her morning nap? I'm only asking as DS slept from 7pm - 5.50am today. Joy! He also dodged his morning nap, so I gave him lunch at 11.30 and put him down for his nap at 12, and he slept until 1.30pm. Hopefully he's now dropped that nap and tomorrow I can push him until 12.30 before having a nap.
Not that I know a hoot about anything - hindsight is a wonderful thing, after all. When I look back over the last year, it seems so bloody obvious when things are changing with DS, and what should be done, but when you are in the thick of it, and exhausted, it's the hardest thing in the world to solve.
The naps and night time are connected, I am sure of it - though tbh I used to bust a gut getting DS to have his 3 good naps a day and it made no f'ing difference to him sleeping at night.
But I am in such a different place than last week, thank you, not only better rested (and almost sleeping through myself again!), but feeling more confident again.
Just in time for going back to work...
