I'm having a bit of a panic about how to keep my 15th month old entertained on a flight in a few days time. I think watching videos on the iPad could kill some time but does anyone know where I can get some small headphones? She's particularly little, wears 6-9 month hats. I've seen some headband things, has anyone tried these and knows whether they're actually more comfortable than headphones or just a gimmick?
