5 month old extremely clingy

This all of a sudden just started within the last couple weeks. I used to be able to put her down and she’d play by herself for a while so I could do the dishes and laundry, or she could go to sleep on her own at night time and sleep through the night. Now she needs my attention all of the time and needs to be held for every nap and bedtime takes 45 mins. I follow her wake windows and everything. It’s just really getting to be so hard and idk what to do. She is a stubborn little girl too and knows what to do to get her way!

Any tips?
