I Have A Three Year Old At Home. She's At

I have a three year old at home. She's at home all day with me - she's not in preschool or day care. I wonder what the ideal schedule for her would be. She's very active and very inquisitive. Lots of outside play time everyday and reading and writing in the home, also play time. However, she tends to go to bed very late and she seemed to need constant stimulation. I think its time for school!!
