Sleep regression 😫

Rubee (10 weeks old) has been sleeping so well at night. I’m talking 9pm-6am. Until now. I kept reading about the 9 week sleep regression and praying it didn’t happen to us. Lol. Then our fucking ac went out. 80 degrees in our house AT NIGHT. Can you imagine a swaddled baby at 80 degrees?? We use fans and get it as cool as we can-but she likes to be much cooler. So I swear that kicked off the sleep regression. Lol. Last night she woke up at 3:45. Tonight, I put her down at like 8:30, and she’s up right now (midnight) I just tried to give her the passy and see if that helps. If not I’ll probably just feed her and start over. She looked at me and smiled so big, lol, so I don’t think we’ll be sleeping anytime soon. How long does this one usually last? Anyone through it yet??
