Wow that is so brilliant his sleep pattern worked so well!
We tried the same but it really didn’t work sadly.
I love how he naturally corrected his own sleep and now it’s a stress free situation. Well done!
We did similar but from age 2-4; he would often fall asleep around 1-2am, but because of his fiery nature and his lack of understanding at that age we couldn’t keep going because of his awful moods and meltdowns. Which was so hard.
But he’s 7 and slightly better now at knowing and accepting when he’s tired.
Love your story and it’s such a triumph!
