My 8 week old wasn’t sleeping great; is now sleeping WORSE. Help 😭

Not sure what the heck is going on, but my 8 week old is suddenly not going down in her crib. If she does, it’s maaaybe 2 hours for her first stretch, and then up every 30-60 minutes until morning.

Nothing has changed. I don’t understand! Is this an 8 week old thing? How did you navigate this?

Edit: forgot to mention that she’ll sleep if she’s on my chest. She was like this pretty much exclusively until around 3 ish weeks, so it’s confusing me as to why she’s regressed back to this for the first time since.
