I do not and will not let my children ride their bikes around the block by themselves. My oldest is only 4, but i know at 5 and 6 (or even 8 or 9 for that matter) my mind will definitely not change. I may be a little on the protective side (or a freak lol) but you really can never be too careful these days. You really never know what can happen, even though you are in a neighborhood that you feel is "safe" you really just don't know who is driving through your neighborhood, or who your neighbors "really" are. Anything can happen. I do remember when I was a kid running around the neighborhood with friends and there were no worries, becuase it was a different world back then. I just don't see letting my kids out of my sight for any amount of time, right now or any time in the next few years (at least). I may be a freak, and over protective, but it is for my kids safety. That said, I have a friend, who let her 5 year old ride her bike up and down her street and walk around, without her supervision (which I completely disagreed with) and she had a neighbor call child protective services on her. So now she is going through a huge thing, that could have been avoided had she kept a closer watch on her daughter. Please be careful, you really don't want that happening to you.
Edited to add more:
Yes, horrible things happened 30 years ago as well, but it wasn't heard of as often. Now, we KNOW this is happening, and WHAT can happen to our children, we are more educated about it and we CAN keep our kids safer now, and I think we all have the obligation to do so. Even if the statistics aren't "high" statistics....I am happy knowing that I am doing everything in MY power to make sure that my children are NOT in those statistcis, however low they may be, those 100 kids are somebody's kids and they *could* be yours, mine or somebody you know. I just don't think you could ever be too careful when it comes to your kids. I do educate my children on safety in a way not to scare them. They know that they are not to go outside without mommy, they know they are to stay close in a store (actually they know they need to hold a hand or the cart), they know not to talk to strangers unless mommy says its ok, they know all of this, and my son is the most outgoing little boy, who I have NOT scared, but have made him aware that things can happen, and that they need to stay by mommy. That said...I don't judge any mom that does things differently, we all have different levels of comfortability here. I am merely expressing my opinions, and answering the question "At what age did you give your child some independence?" in a very long drawn out response LOL. My answer to that question is definitely not any time soon.
About the school bus comment: I do know that I can be overly protective, and my answer to this question will show that I am sure. My kids will not be riding on a school bus until they are not suppose to be legally in a car/booster seat anymore, which is age 8 or 80 pounds. Until then, I will be driving them to and from school.
This is getting super long but I wanted to reply to this remark:
Just thought I would throw this out there...You have a much better chance of winning the lottery than of your child being abducted outside. For those who don't send their kids on the school bus until they are out of a booster seat, you are probably putting so much fear and anxiety into your child!
My children do not know my reasoning behind not letting them ride the bus. We haven't come to that point in time yet. My son actually had a field trip for preschool last year...he was only 3 years old, and they rode a bus without seatbelts. I chose to drive my son and attend the field trip with him, and he enjoyed that even more becuase he felt special that his mommy was there with him. Honestly, your remark really ticks me off and I really don't know how to respond without getting mean. Just know that your statement is completely ridiculus. My children are very outgoing, well rounded children and they are not fearful or anxious becuase they have a mother who cares so much about their safety. They are better children becuase of it.
