Should I wake 2.5 year old from nap?

[LolaKnickers]

She will sleep for anything up to 3 hours if left to her own devices. Doesn't go to sleep until almost 9pm - though bedtime is earlier, she sits up in bed.

Nap time is usually straight after lunch at 12 - 12.30 ish, though sometimes from 11.30 if she has fallen asleep in the car, sometimes, and sometimes later (1.30 - 2 pm)if she has faffed with lunch etc

I have tried waking her before but she is very grumpy for an awfully long time if I do this - more so than if she hadn't had a nap. Any tips?

My DD (2.10) still can sleep for up to 3hrs during the day - about the same time as yours, but not every day now (tho when she doesn't nap she is harder work!). She stopped doing this regulatly about 6weeks ago - so she was certainly doing it at 2.5. I tend to put her to bed at 7pm and she, too, sits in bed and 'reads' for a bit. I don't have a problem with it, i have to say. Is it a problem for you? Does she sleep through the night? If it isn't a problem as such, but you are just a bit worried because she is in the minority, I'd say, don't worry and enjoy the break in the day!

I was just concerned 9pm may be a little late for her to be going to sleep. It's not a problem for me, though she does also get up very early.

so does mine!!! From my own experience, it has not made a jot of difference whether any of my 3 DC's have had naps, gone to bed early, gone to bed late - they all still got up at the ruddy crack of dawn until they were at least 5. But your DD may be different .
I guess its up to you - if she is being put in her room at a certain time (my DD is in bed at 7 but she is still awake and chatting now and likely to do so till about 8) then she is getting the message that this is bedtime. i heard somewhere that most toddlers naturally have an 'awake' time early evening (tho can't remember where I heard this) and it seems to have always been the case with me. You may find, like I have recently, that your DD will begin to drop this nap herself fairly soon.
