This early time is really a time to get to know your bub. Don't worry about routines yet as they can give you a false sense of what 'should' or 'shouldn't' be happening. You are likely to have some natural routine in your household anyway and they will start to learn those. Their internal routine (eg. when they are hungry or want to sleep) changes a lot between now and 12 months so you will just be constantly revising. Keep a mental note of what bub seems to want to do as it will help you figure out when she is upset whether it is fatigue/hunger etc. They seem to 'level up' where all of a sudden they will drop feeds or be awake for longer and strict routines will just make you fight those naturally occurring things. You can introduce some gentle routines like bath, book, pjs and bed at the end of the day but a few months on. But if you can fit it around their natural incinations you will have better success and a lot more enjoyment out of your day then a prescribed routine.
HTH.
