Letting us go places and run around without constant supervision wasn't to teach us independance, but just convenient for mom. She could do what she needed to do in the home with no kids in her hair. We could explore, go places and so forth without her.
We don't live in safe times as those and our kids will become independant regardless as they grow up. Protecting our children from a much harsher environment is more important than their ability to walk to school by themselves. I never walked to school because my school was five miles away, but I'm still independant.
I only went to my piano lessons by myself a few times....I'm still independant.
Really there is no need for you to take the risk of leaving your children to their own devices and open to danger from a much different world just to teach her independance. It isn't necessasry and I think it's irresponsible and lazy. We don't have that convenience that our mothers had....but that's just my opinion.
Check the Illinois Registered Offender web site and see how many registered offenders are in your area...and it tells you which were crimes against children or other circumstances. I live in a really nice area in $300,000 homes and up...but we have about 10 or more within a five mile radius.
That alone should tell you your girls should not be running around unsupervised or guarded. It's a pain and you can't get much done, but that's just the facts for the times we live in.
You want your girls to be independant. Give them chores to do daily that they have to get done on their own. Let them pick out some of their own clothes daily. Allow them to pick and fix dinner with minimal help once a week. Maybe even allow them to prepare a menu, take them to the store to shop, then fix the meal....setting the talbe and everything. Send them to ask the sales person in the store a question. Give them the money at the counter to pay for their own things with their own money. Set them up with a savings account that they have to keep track of and balance. Allow them to plant a few plants in pots and explain how to take care of the plants....tomatoes, some beans, flowers???? Get them a fish that they have to read up on and care for. Start with a Beta/Fighting fish.
There are all kinds of ways to teach our children how to go it alone without taking the chance they will come across a predator, mean kid, gang member, or drug dealer with no one around to help them. It's just silly to expect them to handle those situations and how horrible if something happened while they are walking to the library. I would wait until their teens and then make sure that they have taken a defense course or even taken karate classes for awhile.
Now whether teens should be wandering around unsupervised or not is another soapbox....mine won't be no matter how much they whine and cry about it. A child's brain doesn't develop in the area responsible for reasoning and decision making until they are 18...so why am I going to let them go places in which they have to make hard decisions when they don't have the brain maturity to do a good job????? Talk about gambling and we wonder why teen pregnancy, sexually transmitted disease, drug use, alcoholism, and crime among teens is so high???? Duh!!!! We just throw our kids to the wolves and hope for the best. At least wait until they have the brain maturity to do so.
