DD is a good sleeper which is lucky for me. I think she is a bit of an exception to the general rule and I am waiting for it to all blow up in my face!!

She wakes between 6 and 7am
Morning sleep- at around 9:30am. Normally a good 2-2.5hrs
Wakes at midday
Arvo sleep at 2pm. Normally 2.5hours.
Bedtime at 7pm.

If by chance she sleeps in in the morning then everything just gets pushed back apart from nighttime bedtime. I always try and keep it the same.

I wouldnt wake her up but you may find that that last sleep becomes a shorter one. They get tired and more cranky later in the day so I try and get her down by 7pm so she doesnt get overtired.
