Don’t let her play. Swaddle her tightly and maintain routine. Restart the sound machine, run the mobile, etc. – whatever you do to indicate it’s sleep time not play time.

Also talk to her pediatrician about it.

And don’t afraid to lose your shit but plan for it. Make her safe (e.g.; strap her in a car seat) and walk away. Take the time to scream at the moon, she’s not going to cry herself to death.
