10 week old bedtime

Hi all! My 10 week old passes out every night around 6pm but wakes up at 4/5am every morning. ( waking around 10 pm and 2am to feed). Occasionally will fall back asleep after the 5 am wake up but is unfortunately usually wants to play and be up for the day. I thought about trying to shift her schedule and make her go to bed later but she just passed out at that time every night. Any ideas? I don’t want to push it and have her be overtired and cranky
