That said, I think that with the original post, there are two things that should have been done. #1 is, of course, that Mama should have been keeping a closer eye on sonny boy, especially after he got at the cake the first time. #2 is that the organizers of the party should have arranged for that cake to be placed somewhere that was out of reach of the under-ten club. When I did a cake for a first birthday party, a regular table was used, but when I set the cake up, I moved all the chairs away from that table and commented to the organizers that the fewer people that "sat near" the cake, the safer the cake would be. They all blinked, nodded, and moved chairs off to another table quite cheerfully.
Honestly, though, as a hostess, I do think about the under-ten set when I plan a party. I've noticed that most of the trouble kids get into comes out of boredom, so whether it's a back-yard barbeque or a fancy reception-style party, my family makes sure there are activities and toys for the children to play with, and that the children know early on what is and is not available for them. Since instituting this policy, we've had nary a broken knickknack, and the dollar store loves us. ....unfortunately, we still get scared cats crowding under the beds, but hey, you can't have EVERYTHING!
