I need help

Posting in controversy corner cause I know I'm probably gonna get shit for something and honestly this is the only group that actually replies.. So my 5 month old has her days and nights mixed up and I have no idea how to fix it. I've tried keeping her awake during the day but she will literally scream the whole time and I also read it's not good for them to get overly exhausted. I've been trying to get her on a schedule since she was born and nothing is working. How can I correct her sleeping schedule?
