I'm actually glad that you responded to this one because the OG post mentions Blu Tac and I had never even heard of it until I moved to Ireland. Now I'm seeing it EVERYWHERE and now including in here which is so bizarre. Where I moved from in Los Angeles we just used to call it "Earthquake Putty" for obvious reasons. We used it to put under fragile items on shelves so that they didn't automatically fall down and smash during quakes.
Ang, I hope your little one feels better soon. It sucks having a sick child for sure.
