Bedtime has become a total battle lately

My 5-year-old used to go to bed pretty easily, but the last few weeks have turned bedtime into a stressful standoff every single night. She suddenly refuses to brush her teeth or put on pajamas, and then insists she’s not tired at all. I've tried sticking to our usual routine, reading her favorite stories, even giving her a little extra playtime before bed, but nothing seems to work.

It’s exhausting and honestly makes me dread the evenings. I want to be firm but gentle, and I’m worried this is turning into a power struggle neither of us wins. Has anyone else gone through this phase? What helped you get back to a peaceful bedtime without tears and tantrums?
