18 month sleep regression hell!!

Am

Our little one just turned 18 months today and for the last week has been getting up consistently every night awake for 2+ hours. She’s definitely not hungry, or upset. She just wakes up at first crying and then wide awake almost like she’s ready to start the day. It’s like we are in the newborn stage again but this time it’s worse because they are on the move and so much louder! Any tips? Anyone else experiencing the same thing or just went through it? Please tell me this doesn’t last long!!
