Heyla and welcome to MDC!
As you read through the NCSS you'll find that while she is fond of schedules (to make sure your babe is getting enough sleep during a 24 hour period) she isn't talking about the sort of strict "from this time to this time" type schedule. SO no... you don't need to give up your daily or weekly activities just because they happen at different times! Instead, be responsive to your child and consider ways in which you can tend to their needs during the course of the day. For example, if you know your child is often sleepy in the early afternoon consider wearing her in a sling if you have an outing around that time. That way she can sleep if she wants!
Anyway, a predictable rhythm is often comforting for children. But it's more of a "first we do this, then we do that, then this happens" type thing rather than an "at 9:15 we X, at 10:00 we Y, then at 10:30 we sleep". You'll drive yourself crazy trying to maintain that sort of schedule.

But if you really observe your kiddo for a few days (when is she hungry, sleepy, social, fussy, etc) you'll prorbably get a good idea of what your unique organic schedule looks like... and from there you can adjust bits of it to make sure you're all happy.
Good luck!

May not help, but with 5mo ds...
DD1 has preschool at 9am. So we have to be up and out of the house by then. During the day we have a variety of activities I take dd2 to and obviously ds comes as well. He is often in the ergo and nurses/naps at will. In the afternoon I pick up dd1, and the four of us go home. DS plays, the girls play, I make dinner. After dinner ds has a bath, then slather on lotion, into jammies, and nursed almost asleep. DH holds ds and soothes him all the way to sleep while I put the girls to bed. DS sleeps in DH's arms while we relax, ds wakes around 11pm and we go to bed... I nurse him back out. He usually wakes again at 2am and 6am and I nurse him out each time. At 7:30 I get up and the whole thing repeats.
