We are going on a holiday that involves long haul flights and long drives (gulp) with ds6 and dd2. We normally make them read or stare out the window during trips but I'm realising that this time I may have to get them things to play with. They will need a device each to stop fighting - are leappads worth while, esp for the little one? The games seem insanely expensive. We don't have any kind of tablet so I'm wondering if its worth getting one that the 6 year old can play on and watch movies etc.
