My daily schedule varies some with the different seasons of life, as well as the actual seasons. For example, when I am pregnant, I need a full 8 hours of sleep at night (minimum), as well as a short nap in the afternoon. Also, we tend to sleep in later in the winter when it is dark out, than in the summer when it gets light as early as 5 am.
With being pregnant this summer, I still cannot drag myself out of bed before 7 am, unless I absolutely must, , even if I go to bed early the night before. Not what I prefer, but this, too, shall pass. Yesterday, I finally resigned myself to this reality, and typed up our current daily schedule accordingly. I am the type that really needs written reminders of everything. Also, the more children we have, the more necessary it has become for me to stick to a structure for our daily lives that I try hard not to deviate from.
