Sleep Schedules... HELP ME 😩

Hi! My daughters 4mo. old and used to be the best sleeper. Now she refuses to nap and screams at the top of her lungs (no tears... literally just yells at me 🙄) whenever I have the lights off / quiet time to get ready for bed.

She used to be so easy that I never gave it much thought so I’m not really sure how often she should be sleeping TBH. I need some guidance on what to shoot for and how to start getting her on a schedule.

What’s your baby’s sleep schedule? How long/often do they nap? And how often do they wake up at night?

Here’s a cute pic just cause 😍
