Things that have gone missing around here:
1/2 measuring cup
At least 3 spoons
About 2 forks
Unknown number of Take n Toss cup/ lid sets
3-4 plastic children's bowls
This is a likely occurence when you trust your toddler to put his place settings/ dishes in the "sink" and he mistakes that for the trash.
We caught on and are more diligent to check the trash or listen for his deposits into the sink.
