New mom help!

Let me start by saying I do not expect my baby to be like others but I've heard, read, and been given advice and I am so lost to where I feel like I'm not doing what I need for my baby. She is almost 6 weeks old and I was advised to start bedtime routine and to begin doing things that I would want in a routine during the day. Along with this I was told that my lo would develop her own schedule. She is breastfed and was in some kind of schedule but now staying awake more during the day and she's all over the place as far as what time she eats. Could be every 2 or every 3 hours. Sometimes it's before 2 hours. My sister in law said not to start a schedule until like 10-12 weeks but then read to start earlier so they can follow it. I'm just super confused on what to do. Then I read how worms 5 week olds are taking distinct naps during the day and sleeping 8 hours through the night. Is this typical? If so how do I get this? If not and you have a baby that naps distinct naps how did you get there? Mine will sometimes fall asleep right after nursing and sleep for 2-3 hours other times she will nurse and stay awake then take a cat nap for about 20 minutes until next feed. Any advice? Or just keep everything on demand. Thanks!
