LOL, no kids, just fish and a dog who believes hole heartedly he's my kid, the rock and wood were on the shelf for months at my lfs and had never been in a tank, don't feed live feeders, and honestly don't have a clue how it got there, or how it's survived with these cichlids, not a very friendly group. But my Tandi did break out with ich about 2 or 3 months ago without any known cause or warning and had been well established for months, so i'm thinking he could have been the culprit, or whatever was added with him, who knows.
