Hiya Hon,
We have been here before. It sounds like an UT/OT cycle to me. What confused me was that Sam was/still does sometimes settle well at BT but still wake ahead of time. The same as when you want them to cap their own nap you can put down slightly UT KWIM
It was the same thing for us. What is DS morning A time right now
What is his usual night length
IIWM I would go for 5 hours morning A time and cap his nap at 2 hours. Then make sure his A time to BT is a good length to ensure he isn't UT, but not too long as to risk OT. Easier said than done eh
. You didn't say what time he is waking right now, so maybe he will have to have EBT if his nap is too early in the day after 5 hours A time
Anyway this is what worked for us at the same age. I was letting Sam sleep more than his 2 hour nap if he seemed to need it but it backfired and then became a viscous circle, especially since after a few short nights he would always grab at a longer nap if allowed to so something had to give.
Does Zac tag on sleep
I have come to believe that a longer night and shorter nap is much more restorative than vice versa, although I do understand what you mean by unbroken sleep being better than a longer broken night, I think in the long term that doesn't work.
Cheers Honey.
