Hi melissa - not sure if this will get to you in time but IIWM I would definitely stick with yesterday's nap time. She has slept a great night in order to catch up on the sleep she's lost at nap time over the last few days, so its more about catch up, rather than her being well rested already IYSWIM? She could still be a wee bit OT so its a big risk to push her on any later, although I do understand the worry about her being UT & doing a short nap. Sleep begets sleep, so the better rested she is, the better she should nap. Lets hope it went well.
We tried for a CN but we were'nt successful, so we went with a 6pm EBT. Aarrrggghhh!!! I am REALLY scared we may be up at 4.30 or 5am tomorrow. Watch this space!
