This was Ben's idea - I think it started because the trash cans have wheels. He is entranced by wheels. I would not have thought of this job for a 3 1/2 year old.
He pulls the empty trashcans in from the curb
the whole way back to their hiding place.
Our house is three apartments - we live in one - so he gets to pull two or three trashcans every week, plus heft a few recycling bins.
He loves it. I love seeing his eager face and his satisfaction at doing a real, helpful job.
Before Ben, my husband and I would put off bringing in the trashcans, just pulling them into the passageway in front of the gate; sometimes they would stay there until the next trash day, blocking any stray idea to wheel out our bikes. It's amazing the energy a household gets from doing jobs in a timely manner!
