Welcome to the group! How old are your kids? Mine are 8 and 4. I try not to think about this since they are things that are out of your hands. I still have a hard time letting DS walk five houses down the street to his friend's house by himself even though I know he's fine. I try to focus on the things that I can do to influence them in a positive way, teach them to make good decisions, how to defend themselves, be proactive about their lives, etc.
