Our 4 year old never did this. At bedtime she basically goes full panic mode and starts crying and screaming for hours. We had to put a lock on her door to keep her from coming out.
She ends up falling asleep every night by the door, then usually wakes up around 4:00 or so and then starts screaming and crying again. We were blessed with a first child who has done super well at bedtime for most her life, so this is unchartered territory for us. Any suggestions on how to deal with this? Words of encouragement?
