We have the lamp in my 4 y/o's room on a smart plug and set it to come on at 6:45 during the week and at 8:15 on weekends. She gets up early but knows not to come wake us up before the light is on. Usually she just plays quietly in her room which is fine with her and certainly fine with us. She also can go down to the kitchen and get an easy snack (applesauce squeeze pack or string cheese) if she's starving and, obviously, go to the bathroom.
