Hyper little girl

Patient: Hi my name is Kelly I have a 4 and a half year old little girl.. She is very very hyper and loud and is now throwing fits to the point where the child care center is unable to control her anymore.. she goes to sleep at 8 in the evening and is up at no later then 4 am it doesnt seem to matter what time she goes to bed shes up at that time every day .. I am not comfortable with giving her medicine to calm her down so I have not even tried to see a doctor about this .. I was wondering if there are any natural types of things that I can try either to calm her down or help her sleep I think If she had a good nights rest she may have a better mood through the day … thanks
