As my boys have got older the travel kits have changed, but are still a backpack. They put books, snacks, electronic games, music players, etc into them and then if we are on the road, or having to hang out somewhere for hours at a time, they have something to do. Worked well when they were toddlers and still works well now they are teenagers. In fact, I carry my own entertainment kit with me – which consists of a book to read, small craft items to work on such as cross stitch, crochet or knitting, a portable gaming system, my camera and a notebook and pen. I am hoping to add a netbook computer to this soon. This helps keep me entertained when the kids are at the park playing which means they can play for as long as they want without being dragged off because I am bored.
