She won’t wake up

My daughter is 12. And to wake up on school days she has an alarm, but it never wakes her up, I always have to go in a call her name rock her back and forth, annoy her till she finally gets up. She goes to bed at a good time, she gets 8 hours of sleep, but she just won’t get up Any tips to help me get her accustomed to an alarm and not me getting her up would be appreciated.. via /r/Parenting https://ift.tt/2mQuSIl
