'No, don't touch!" These are probably the most infuriating words for young children to hear when they are being dragged around an art gallery by their parents.

Their frustration is understandable. Often, they find themselves standing in front of an unimaginably eye-catching creation — maybe an oversized sculpture or a colorful painting — and an almost primal urge makes them reach out to touch it.

Socialized adults may manage to curb such instincts — but it's not so easy with young children (at least in the case of my two children, aged 1 and 3, who, to my consternation, have stamped their fast-moving sticky paws on a trail of artworks across Tokyo).
