Today the boys and I cleaned with the hopes of finding a lost library book. We picked up toys, cleaned out under the beds and moved the couch. Under the couch among the tinker toys, puzzle pieces, legos, and other various items I made a discovery. We have a family of Littles living under our couch. I can think of no other explanation for the array of crumbs under the sofa.
Alas, the library book is still missing, but the crumbs have all been vacuumed up.
