bedtime for toddler entering school ? my almost 4 year old is starting school in Aug. she will have to get up around 6am, what time is everyone putting their little ones to sleep?

we don't eat dinner till 6 630 since thats when daddy gets home , so we can eat as a family. But even spending an hour with daddy after dinner and relaxing time to unwind before lights go off it's already 9! I know what they recommend but how many hours do you really make sure your child is getting???
