Happenings at Gnome Hollow: Bed Time Rhythm

Our bedtime song is "Twinkle Twinkle Little Star" and as soon as I start singing it I have one child that literally runs to bed, banging on any closed door in his path until it is opened, he grabs his blanket from a basket on his bookshelf and tries to climb into his crib, where he sleeps peacefully though the night and wakes up talking and laughing to himself until I come to get him. My other child runs in any direction she can away from her room, and tries to hide to avoid the dreaded bedtime. Although she is 19 months old she has yet to sleep through a night usually waking at least 3 times, with blood curdling screams. We have tried a night light, the overhead light, a white noise machine, bedtime tea, lavender diffusers, amber teething necklaces, putting her dolls to bed, singing to the dolls etc etc, nothing seems to giver her a decent nights sleep (or me). Does anyone have any ideas on what may help her?

She is an adopted child and did have a rough start in life we are not exactly sure what has happened to her, and what she has witnessed, but I do know she was often left with strangers and in and out of foster care before she came to live with us when she was 10 months old. As of right now we start winding down after dinner, we have a story, then they are allowed to play for about an hour, then bath time (with lavender oil) another 1/2 and hour of quiet play then its "Twinkle Twinkle Time".

Here's a few pictures of our day when we aren't fighting sleep:
