Edit to add: Bear in mind that this story is for a two-year-old. Toddlers love and need repetition, so if this seems repetitious, well… that’s because it is repetitious. Did I mention it repeats itself? Just so you know, it does that. A lot.
Once upon a time, there was a little backhoe. He was a very little backhoe, but he was a good helper. One day, he went to a construction site near his house and watched all the big construction vehicles doing their jobs. The huge excavator scooped dirt into a gigantic dump truck, which carried the dirt away and dumped it into piles that the bulldozer smoothed out and moved around. The cement mixer twirled all around the site, pouring cement from his chute wherever it was needed, while the mobile crane lifted beams and things into place with his long boom. The little backhoe was very excited to see all this work, and after watching for a while, he wanted to go help.
