The culprit? Sean, our three year old.
Rather than overreacting, I have asked Sean some questions to try to understand his behavior - Is he hungry? Does he know he can come to Mommy or Daddy for food? Does he know he can not eat in bedrooms? Besides being able to tell me that the food is for him, not Ben, I am not sure what is going on here.
I just looked at a few sites about hoarding food and it sounds like at this age, it can be common for children to collect things. At an older age, like 7, it can be a controlling parent issue. If the child has had a time in their life where food was scarce, they may also exhibit this behavior.
And when a 40 year old mom hides her favorite candy, Milk Duds, a special present from her own mother, well that's just normal.
If anyone has insight into this behavior or into the psyche of a three year old boy, please comment. In the meantime, I have the exterminator coming so we do not have a bug problem!
And last but not least, Ryan's viewpoint: We should be proud that Sean put the pepperoni in a bowl.
