What a fun morning surprise for A & S! I created a fun, with moving parts, bulldozer!
I had a fun time building this bulldozer from cardboard boxes. There are steps at the back so they can climb into it. It is complete with a spinning steering wheel and a bucket that lifts up.
I remembered too late that I had some hinges that would have worked better, but that is what I get for not pre-planning. It will have to be a post-addition.
Update: after the bucket fell off they realized it makes a great sled! Time to let them play & then reattach the bucket!
