Train to sleep early!

I just got back tonight from work around 11:20 pm and my daughter still up waiting for me. I's so worried about this because she is going to School for JK in 2 months. It's been like this for quite a while now. I need to train her to sleep early so that she will wake up early too. When she sleep too late she will wake up late too that's why I guess she still up when I get home. Anyway I'm going for day shift next week that way I can train her.
