To my surprise it seems like we are in the very beginning of the 1-0... by which I mean, Audrey can no longer manage both an 11-12hr night and a good nap - either the nap or the night is cut short.
It seems that any length of nap (I haven't tried less than an hour) will cause her to be awake until at least 8pm, often much later. She's woken in the morning at 7-7.15. On no nap days she copes admirably, and will do 12-13hrs. We haven't done more than one NND in a row - usually not more than one in a week.
She does drive me a bit nuts in the evenings. It's fine if she's just chatting with her 'guys', but when she calls me back at 8.30pm... or when I think she's been asleep but I hear "Hi Stan! You going bed now?" when he goes in, it's frustrating. I feel like she's not getting 'enough' sleep but she must be, really, she is fine and happy, and she has the opportunity to sleep. She never really seems tired when we put her down, either for nap or bed, unless it's a NND.
On the other hand though I think we need a bit of a break from her! She is pretty full on - which 2.5yo is not - and it's exhausting to keep going like that all day without that rest time. I know we should probably be waking her after 45 mins of nap or so ... but it is so so so hard to break that peace and quiet and deliberately wake her up! I am trying to cap her at 1hr but even so, the bedtime larking about continues.
