Worst sleep regression ever...who else? 😩😭

For the last week and a half or two weeks my son has gone from waking 1-2 times a night to 4-5 times plus the occasional (few times a week) 2 ish hours of being awake in the middle of the night. I'm awake during the night for longer than I am asleep. I am CONSTANTLY tired and irritable. He naps really well during the day so I don't understand why he's sleeping so poorly at night. Please tell me I'm not alone.... I know it will end soon, just looking for someone else experiencing something similar 😪
