Some people have done it, but I think this is less effective because if we just buy stuff for her. No learning or recognition process with bitcoin. Because we are using bitcoin still, he only received the goods you buy with bitcoin become less fit, I guess.
But if you bought them bitcoin, and guide them to buy something online with bitcoin maybe it worked

I think that way would somehow be effective if you try to gave them a bitcoin and purchase it with the things they wanted because it might caught her interest if he bought something with bitcoin and she might be curios and ask you on what way which you can earn bitcoin to be able to purchase online or on physical stores.
