Just saw this thread. Knew I wasn't alone.

These are items I have purchased for my Nephew. Light when he was 5, Scrapivore now that he's 7. I also place thos little push on LED lights on his school backpack. When the batteries are drained or the lights are damaged, I put a fresh one on the bag.
Do gear checks for functionality every chance I get to make sure his gear functions properly when it's most needed.
