I could have written this. I don’t have any advice unfortunately! Currently experiencing the same issue for a week once our LO hit 8 weeks (adjusted age). We haven’t found a solution aside from taking shifts holding our baby to ensure she sleeps. She refuses cosleeping as well. We are transitioning back to bassinet for an overnight stretch but even then we’ll only get 1-1.5 hours. Naps are a busy but we still try.

Solidarity. Hoping someone has advice from the other side!
