I deliver mail and my 3 year old son thinks it’s pretty cool, so I decided to go to home depot and got a big cardboard box. I made it fit around his power wheels truck (3×5). I cut it out to look like my mail truck.
I painted it white and put some postal service print outs that I printed from the computer on the sides and back, then I painted red and blue stripes around it cut out windows.
I let him wear my shorts(which were pants on him) gave him one of my shirts and my visor so he could look like a mailman. He rode in the local Halloween parade and he won. He was so excited.
