Routine with a newborn

I know I shouldn’t compare but it’s inevitable! I feel like other people have more of a routine with their babies but I don’t understand how at such a young age! My daughter is almost 4weeks, she eats every 3 hours or so and in between feedings she is usually awake for 30min-hour then sleeps until time to eat again. I’m a ftm and not sure if this is normal or if we should have more of a routine (awake for longer, put down for naps at certain times, etc).
