We have a strict bedtime in my house (and I just made it an hour earlier for when school starts!) My girls have their baths at 6, and are in bed by 7. We are going to have to be up around 6:15 am when school starts, so I want my oldest to be somewhat prepared!
My boys don't have a bedtime during the summer months. During the school year, they brushteeth and go to bed - short sweet and simple routine. They usually shower earlier in the evening or sometimes a little before brushing teeth. Lights out for my youngest is 8:30 and for the oldest is 9:00. They get up around 7:30 for school.
