ok well we have been doing this for about a week so update and advice....
generally things have been ok/better in that she has not been up to any 4/5am shenanigans and if she does wake and make a noise which is pretty normal for her, she goes back to sleep.
Yday she slept later and was only woken when H called out (loudly!) at 7.15am. She clearly would ahve slept more, was yawning for a while etc but then did not nap despite PD at normal time so we did an EBT of 6.30pm which tbh is the earliest we tend to go with either of them. She had a pretty restless night which is v unusual for her on a NND, usually we might hear her once but she sleeps fine. So then today she was clearly tired and did her usual nap (capped to 1 hr) as per plan and I PD for bed just after 7pm.
So....carry on with the 1 hour naps for a bit longer? I wonder whether the fact she did not sleep well last night after a NND is because the hr naps are a bit short for her and she is getting OT..maybe she would benefit from 2-3 NND's but on the days she naps to have longer i.e. not be woken? Tricky isn't it...
Do you think I should just stick with what we are doing for another week or so and then reassess?
