When did you start a nap schedule with baby?

Megan
Hi! First time mom here! I have a 7 week old and I'm wondering when you mommas started a routine of putting your newborn down & at what time? I'm a stay at home mom taking online courses this semester for college so anytime works for me. My little one is usually up by 7, takes a little nap around 9 after she nurses them another longer nap around 12. I know all babies are different but I would just really love to hear your stories and advice! Thanks so much in advance!:)
