In my experience, woke my daughter up was not so difficult, but to made her get up was pretty difficult. When she was young, every morning I woke her up, but she stayed in the bed until I urged her again and again. I got so tired. It made me crazy. Once, I had read a book about how to lead your kids. I tried the strategy which the writer had offered. Next morning, I woke my daughter up as usual, I told her the time, then I left her to do my own things. I didn't urge her again. That morning, she was later for school. The next morning, I did the same as the last morning, for afraid of be late again and got blame frome her teacher, my daughter got up immediately.
