4 month sleep regression! Send help!

I’m at my breaking point with this sleep regression. She was sleeping through the night at first. Then she started waking up at 2am once being put down at 9pm and then again at 5am and then sleeping until 9am. Now she’s up at midnight 😢😢 i don’t know what to do. I just want her to sleep through the night again!! Also now she’s not napping as long. She went from taking 1 hour naps to Taking 30 mins naps. She only wants to nap in my arms. Mommas at the edge 😢😢
