Thanks ladies. Very helpful as ever.
I don't even think she is LSN as she is getting 4hrs of day sleep most days, she just seems to like it mostly in the first nap. I never aim for a one nap day and she always wants to sleep around 9.30, definitely no later than 10.
In theory I can do EBT but the days she skips the nap are normally if we are out for afterschool activities so often by the time I'm home it's 6pm anyway and often 7 by the time she is asleep. If I put her down too early she gets woken up by the boys going to bed anyway. She always sleeps if she goes down in her own bed.
I guess I'll just stick with it until the nap shortens or she starts refusing the second nap at home? Then I'll move it later.
Actually the boys finish school in a week so we'll likely be out more and she won't get a chance to have a long nap so much.
