Parenting Weigh-In: Getting your child's hair "did"

As of RIGHT NOW, I'm starting a new series - Parenting Weigh-In(s). Basically, I want to hear your thoughts on certain subjects. So, please, as will ALL of my posts, please feel free to "weigh-in" in the comments area. In fact, I'm begging!

First up: What do you think about little kids getting their hair "did" as little kids. I don't mean hair cuts and rollers for church - I mean: highlights, colors, etc. What's acceptable? What's not? Do you have any personal age limits? And, why do you feel the way you do?

*Please do keep in mind that everyone has a right to their opinion. This won't be a bashing or name-calling fest. I would just love to hear what you think and your reasonings! Ready? Go!
