Both of my children are early risers, which is perhaps the only thing they have in common. Because of their age gap, my son goes to bed two hours before my daughter. While he hates it and vocalizes his complaints — it's a non negotiable. Six-year-olds need more sleep than 11-year-olds. As they grow older, their bedtimes will continue to shift later, but won't likely match until they are teens.
