Well, we have just completed day 8 NND in a row.

No obvious signs of OT either, reasonable ONS thus far, (think our lowest was 11hrs? Most have been 11.5 though, which isn't too bad I guess). But, we did just have a NW 1.5hrs after bedtime tonight - I'm guessing it was a night-terror, as poor wee man was screaming and rolling around, not acknowledging us being there with him, lasted 5-10mins then he went back off to sleep.
I'm sure he will be a bit OT, this is un-charted territory this long without a nap! It's not through lack of offering - I have given him the opportunity every day to have a nap, but he doesn't.
My husband just questioned if we should be encouraging a VERY late nap (eg: 4pm) and a later BT...

To me, that is still delaying the enevitable, however. He has always needed more A time in the morning, and can do much less before BT. His recent naps have been around about 2.30/3pm, which is on the late side anyway, if you ask me! He will still go down about 8pm though... WU somewhere around 6-6.30am usually after a nap day.
What do you think? Should I just keep going, offering the nap, sticking to the set BT? (Currently 6.30pm, or fractionally earlier, as it's taking him longer to settle the past few nights - surely that too is a sign of OT creeping in?)
Argh, wish these kids came with an instruction manual at birth!! Sleep is sooo confusing!!
