My youngest is 7 and she goes to bed at 7:30 on school days and 8 - 8:30 on weekends. We have supper between 5:45 - 6:30. My 12 year old goes to bed at 9:30 on school nights and 11 on weekends. Is your 5 year old in kindergarten? I personaly think 9-9:30 is late for a 5 year old but that's just me.
