I always wondered about the geography. A beanstalk grows into the clouds. Does it pierce through the atmosphere? Is the giant's land in another dimension, on a floating island, or just on top of a very high cloud? And how does the giant's wife get there? Is she a giant too? She's often portrayed as just a very large woman. If they're the only two up there, where did their wealth come from? Did they conquer it? The worldbuilding raises so many questions the folktale isn't interested in answering, which is part of its charm—it's a pure symbolic landscape.
In psychological terms, the cow is the superego (practical, survival-oriented). The beans are the id (desire, impulse, magic). Jack, the ego, listens to the id (the strange man's offer) and angers the superego (mom). The resulting beanstalk is the unfolding of the unconscious world. He gets the beans by letting impulse override caution.
If you have a Kindle or use the Kindle app, you can find countless free versions on Amazon. Just search 'Jack and the Beanstalk free' in the Kindle store. Many are compilations like '50 Classic Fairy Tales' that are permanently free or priced at $0.00.
The formatting for these can be hit or miss—some are perfectly fine, others are poorly edited. But it's incredibly convenient if you already use the ecosystem. You can download it in seconds and have it on your device forever. I've amassed a huge library of free classics this way.
Just a thought: sometimes the best version isn't online. Checking out a physical book from the library lets you control the pace and discuss the pictures. But I get the need for instant access! Digital is a lifesaver on some days.
If you're tech-savvy, you could use an AI image generator to create custom illustrations for your own telling. Prompt it for 'a friendly giant looking confused, cartoon style' or 'Jack meeting a giant who is gardening, digital art.'
Then, use a simple slideshow app to sequence the images and record your own narration over them. This is obviously more work, but you get a 100% customized, gentle version. The giant can look exactly as non-threatening as you want. It's a novel way to use online tools not to find a story, but to build the exact story you envision for your child. It's the ultimate in tailored content.
My go-to is Storyline Online, but I don't think they have 'Jack and the Beanstalk'. They have actors reading picture books, which is amazing. For this specific tale, I second the YouTube recommendation. You can find a video of someone like 'Ms. Booksy' or 'Cool School' which are super energetic and silly. The pictures are part of the animation. It's more entertainment than a quiet reading session, but it gets the story across.
