I went with me grandson of three. He liked the 'playhouse' but otherwise there were very little things to do for kids his age. Too much of a museum ... perhaps the designers could connect more with the visions of children that love Miffy ...? As an adult I really liked the lay-out, but I would recommend to take a look at the target group you're building the exhibition for. Now to me it feels like a bit of a no-mans-land.
