The buddy system is when you divide your kids into pairs. When we go somewhere we usually use the buddy system. I am with Andie and Shelby is with Cole. You are not allowed to leave your buddy. When we were in the airports traveling to Florida we held onto our buddy's hands. You aren't allowed to let go of your buddy - even if they try to eat you. Must Hold Hands.
That is how the buddy system works. We use it in airports to be safe.
You should try it.
(Shelby was the one having trouble with her buddy- he's part tiger)
