hi there, how old is your dd?? but i see you will be on a 3hr routine, so it would look something like this:
6:30 eat
7:00 activity
7:30 sleep
9:30 eat
10:00 activity
10:30 sleep
12:30 eat
1:00 activity
1:30 sleep
3:30 eat
4:00 activity
4:30 sleep
6:30 eat
7:00 bath
7:30 bedtime
10pm DF
it would look something like that more or less.
if she wakes a bit earlier hungry let's say at the 2.5hr mark, its ok, this would be just a guideline, and if it is 9:30 and she hasn't woken up, then yes you should wake her up. hope this helps
