I need sleep! 😩

For the last few weeks my daughter has been waking up in between 1am and 2 am every single night! She cries and screeches so bad, I try and ignore her for a while to see if she'll go back off but she sometimes can go for hours!! As soon as I enter her room she will laugh and start playing. Then I'll leave and she screams again. She was an amazing sleeper before this. I'm exhausted
