Thanks so much for taking a look at this ladies - my gut says NW is UT and I need to cut the CN to 20m, but don't want to make things worse so would love 2nd opinions... I have attempted to wake him at the 20min mark the last couple of days, but he sleeps on through to the 30m, so I doubted myself and wondered if he actually needed that extra 10m?
He is 10 months this week and this is roughly what the last few days have looked like - he has been recovering from his virus, so A times have dipped slightly and I haven't capped any of his morning naps as he needed the sleep;
w/u between 7:10-7:30
1st A - 3hr35 (this was closer to 4hrs before his virus - but he is pretty desperate for his bed at this point at the moment)
Nap 1 - 1hr20
2nd A - 3hr15/30
Nap 2 - 30m
3rd A - 4hr15
BT - between 8:15-9pm (as couldnt get him down any sooner!)
NW - after 40 mins & awake for 40 mins, then he is down for the night.
This is pretty different from a few weeks ago where the 1st two A times were closer to 4 hours and the last one was 3hr45m and he went to sleep no problems.
Something is obviously shifting routine wise and i'd like to work with his natural cycle, not against him with whatever I do!
I'm 99% sure this is nothing to do with pain, as he tends to wake frequently in the night when it is and at the moment, he is out for the count after that first wake up

Oh and I should mention he is LSN and rarely does longer than 10/10.5 hours a night... also for this reason I want to keep the bedtime on the later side (8pm onwards)
