I think there's a few issues going on.
First of all, since 1-2 wks she started to get up a lot from her bed with excuses (have to go to the bathroom, thirsty etc.) so by the time she really gets to sleep it can be 8h30pm sometimes. We try to put her to bed at 7h45pm.
Also, this week she started a new daycare. (which she likes though)
Her routine is :
wake (used to be 7h00-7h30am) - now it's 5h30am
lunch 11h30-12h00am
nap 1h00-2h30pm
supper 6h00pm
bedtime 7h45am/8h00pm
Also, I wish they would sell the Gro-Clock in Canada...
