DD is 26 months. We did sleep training around 7 months and she's slept pretty consistently well since then. But for the last couple of weeks she does not want to go to bed!

For naps we put her in her crib and sometimes she'll sleep and sometimes she stays awake and talks. At bedtime she wants us to stay in the room and we do. She's happy for 15 minutes or so then starts begging to get out and cries hysterically. It's like she can't shut her mind off. Any tricks to help her calm down and go to sleep?! Thanks!

(her schedule: wake around 7:30, nap 1:30-2:30 or 3, start bedtime routine around 7:45, in the crib at 8:30, usually doesn't fall asleep until 9 or so)
