18 months old waking earlier and earlier?

[buttonbaby]

My DD now 18th months dropped to one nap at 11 months (I did try a few of the tips giving to hold on to it…worked for a very short time and then she started refusing eve nap again) and it was a very smooth transition with her taking 12 hours sleep at night and one long 2-3 hour nap during the day and never showing signs of tiredness unless very close to nap times.

In the last few weeks her naps are only 1hr and a half (Which I know is fine, just shorter than what she had) plus she is waking earlier each day….not very early but she is waking early for her and I am just wondering is there a reason.
She was waking at anytime from 7:45-8:30…never earlier that 7:45, then in the last 2-3 weeks it started as 7:30 for a few days, then 7:20ish, then 7: ish and now is 6:45ish…so its getting earlier and earlier.
Just wondering what could be possible reasons for EW’s at this age???
(She was teething a few weeks ago but think her teeth have cut through and are not causing any problems at the moment.)

Many Thanks in advance,
Fiona

What's her morning A time compared to her afternoon A time?  I ask because when dd1 went down to one nap, her lunchtime nap ended up being quite late meaning that her morning was really long and her afternoon was really short and we started having trouble with her settling in the evening which led to her being OT and waking earlier in the morning.  When we moved her nap to balance out her morning and afternoon the problem completely disappeared and we went back to her sleeping until we woke her in the morning.  Could that be happening to you?

Hi Clazat and thanks for posting.
well morning A time was 4-4 and a half hours and she could sleep up to 3 or 3 hours 40 hours but 2 would be about average so her evening a time was about 5hrs sometiems 5&1/2 hours so her eve a time is longer...should I make her nap later (is now about 12:30/12:45ish)?

The above were her a time before EW's.

It might be worth pushing it back so that she has a similar A time in the morning and afternoon for a few days to see if it helps. 

Do you mean that she can sleep for up to 3 hours 40 mins?  If so, that might be the problem, as that's a huge nap for the day.  I tried to make sure that dd1 only had 2-2.5 hours to ensure that she slept well at night.

No she used to and when she did it was never a problem...she has not being doing that for a good while now and well before the EW's started so that is not what is causing the current problem. It was great though every now and then she would have an odd nap of 3hrs 40(always exactly 3 hrs 40) and still go to sleep as usual that night...those days are over now. average of an 1h and a half now.
