I believe that when you know better, you do better. A 6 year old child is safe in a high back booster, safest in a 5 point harness! Don't be in a rush to move them up because a seat is what they are used to, they don't know any different yet. If your child can't safely use a seat belt 100% of the time the correct way, put them in a harness. Keep those babies safe!
