I tried about 10 days, 3~3.5h from wu for 30mins, then second 3.5A, with 1.5h nap.
re long-short, the longest A is 5h now, getting 1.5h nap, if A was shorter than 5h, nap was short like 1h~1h20min. I think you mean push him to 11:30 is based on wu around 6~6:30,BT 19:00? so first A should be at least 5.5h, maybe 6h, that's mean heading to one nap day ?
I never pushed to 11:30, because I haven't get pm CN refusal. after a 1.5h nap,he always accept cn after 3.5h, maybe based on poor night,maybe chronic fatigue for UT-ot loop.
I also found in recent logs that total sleep is around12.5h maybe, don't know he drops his sleep need or a result of OT.
I know the book mentioned for lsn, any sleep before 12 will steal sleep from late night, but is it the only way to do? like Kate's JACK, he is super lsn, but he did 1.5h at 10:30, still got great night.
now it seems it's hard to try the theory, cos for long nw early moring, at 6:00~6:30, sometime he was woke or just fell asleep half an hour later, I cann't prevent sleep in ,if woke him , he couldn't keep awake till 11:30, maybe I need a chance to get it.
in fact, Kate thought UT ,so suggested me push ,push, push,too, but I am worry about OT, so not brave enough to push so much, the reason I dont dare to one nap is I haven't getting nap refusal as I mentioned above, so not sure if he is ready for it.
if he can handle first A 5h easliy, then 1.5h nap, then handle 3.5~4h, doesn it mean he can handle 5.5A, then 2h nap, then handle 5h?
kate, what was jack's one nap day looked like at 10~11month? This is only thing I haven't tried. if I can get a STTN, I will brave to try it for one day, it cann't be worse than now.
Martii, suddenly another idea, if I want to try one nap day but no chance from 6:00~6:30, could I let him sleep in as he want on moring(at least he rests well , could handle long A), but BT late too? just like after nw, he may wake himself 7:30, nap from 13:00~13:30, aim to 2h, then BT20:00, is it crazy?
