How do I talk to helper regarding her wake up late ? Everyday

Hi, for me last time i hv a helper too and i found out that she waking up late so i walk in and call her wake up and she was shock to see i wake up before her. After a few time of me going in waking her up she auto wake up 6am .For me i buy a alarm clock and set the alarm for her and let her know that she must wake up at 6 , sit down and understand what the reason that cause her to wake up late , try ask her what time she sleep every night after she went back her room (as a care n concern). A timetable will be good for her so that she know what she needs to do the next following day so she do need a good sleep inorder to be fresh tomorrow . The last resort is to talk to agent
