Curfews are an important discipline at any age. It teaches children that what your family rules are. It teaches them to respect the parent. And, it teaches pride when the see that they had achieved that parent's respect. The issue with curfews is they can start at a very early age. Most people think that curfews are only for teens. The reality is that they start with play dates. They start with being on the playground, when mom and dad say it's time to go. Your words are your rule. And, that starts teaching them something at an early age, that when they get to the middle school and high school age, it might keep them a lot safer.
