I'm surprised no one has mentioned the Tonuino project yet. For those looking for a DIY alternative to the Toniebox: it's an open-source project based on an Arduino, MP3s, and an RFID reader, allowing you to build your own custom music and audiobook player for kids.
My children absolutely adore their Tonuino box, and the community around the project is fantastic, constantly sharing creative and impressive builds. If you're a bit handy and enjoy a good DIY project, I highly recommend checking it out. https://www.voss.earth/tonuino/
