I am sneaky, if I can find out anything about what a child likes then I do and I put that into conversation and I frame it in a way that suggests I don’t really know much about it. For example if a colleague tells me the young person likes 1Direction, I might say “Harry Styles is in 1Direction. He’s the one with blonde hair.” Then the young person tells me how I have got it wrong, “no Harry’s got brown hair” and will hopefully open up to me.
