THe start time for high schoolers definitely needs to change. They should be going to school AFTER the little ones. Teens change to a night schedule. Even when my oldest hits the hay on time ( early, by 9) he cannot get up because his body is on its own clock. Working on waking him between 6-7am NOW to help him adjust to the 6am wake up time for upcoming school day. ( He is back in school by AUg 20th)
