Helpppp

I’m trying to get my daughter into a routine to go to bed at 8 or 9 pm( but not sleep train). I give her a bath at 7. Bottle at 7:30 and read a book at 7:45 every night. She will take a nap and then wake up at 9 and then she’s up till 12 or 1 am before I can get her down to bed. Any tips to keep her sleeping(after her feedings throughout the night) after 9. She’s 15 weeks.
