HELP! need advice

My baby girl is 6weeks and she sleeps throughout the day for 2-3 hours sometimes 4. Eats every time she wakes up. However everyday at 9PM she's wide awake and will not go to sleep. Ends up falling to sleep at 2 or 3 AM. She cluster feeds towards the end of her night shift before she falls to sleep. I try waking her up during the day and she will not stay awake. Any advice? This momma needs to sleep😴
