I would definitely get one of the older kids as a buddy to walk with your child. I think at Kindergarden age they are perfectly capable of following safety rules, however even a few houses away kidnappings can occur. I know it is not something you want to think about, but there was just a little girl near my dad's that was abducted over the 4th of July while watching fire works with her family sitting relatively close. Teaming kids up is always safer! Good luck and congrats to your child on starting kindergarden. That is always such a big and fun milestone. My oldest son just graduated K last year.
