If it’s priceless “artwork”, or high end “artwork”, it should be insured. Who displays such objects insecurely, is at fault, if it is accidentally knocked to the floor. Accidents happen; that’s what insurance is for. In this case, the sculpture IS insured, and it was NOT secured or enclosed in any protective manner. And it was GLASS; the kid could have been cut to ribbons. Insurance would have been liable for any damages of THAT kind, as well. Anyone who has kids knows they can get away from you and get into stuff pretty quick. This was a wedding reception, where guests are family and friends. You don’t glue a five year old to your hip in those situations; you keep your eye on your kids, while watching them gravitate towards each other and play, while you adults visit with each other. Anyone who thinks the insurance shouldn’t have to pay, either has no kids, has the most unique kids in existence -— ones that have weird gold halos hovering over their heads, or has kids too afraid of the world (or their parents) to act like normal kids.
Actually I DID glue my 5 year old to my hip or that of a responsible adult. And I was never where such an expensive item was.
Parenthood is about vigilance.
