Let's hope so, vicki! We got 1h35 today, which I am still very happy with, but is sadly consistent with any other time he has had a good spell - we get 2 or 3 really good days, then a couple of days which are fine considering how badly he sleeps and then it gradually just gets worse and worse... I'm not really sure that I identified the 18 month regression (although it did cross my mind last week when his sleep was just crazy bad) because we have never had good enough sleep to regress from!
How was bedtime, becky? Did you go early? How do you feel about trying to ap her back to sleep in the morning when she wakes early? I'm still not sure if it is a good idea, but most mornings I end up sleeping on the mattress in x's room from whenever he wakes up until it is time to get up at 6 - he does go straight back to sleep if I am in the room (he has never been one to go back to sleep with me, so I don't really have many ap options) and so we are getting much more sleep that way, although I am concerned about what happens in the long run. I'm just wondering if it could at least help you get miss m to a sensible wake up for a week or so so that you can push the nap later and therefore bedtime as well.
