Apple (and other brands) needs to bring back IPods. Kids should be able to listen to music and audiobooks without having a cell phone or a device that also serves as a screen for playing games, texting, or using the internet. Let kids be kids!
@cmconseils look around: there are alternatives
My kid has an ocarina player: mp3, no internet, can work as Bluetooth speaker. When it turns on it is limited to 75 dB (no damage to ears).
She has been using it since she was 3, independently, and she loves it. Helps a lot during car trips. I think she will be using it for long. And she doesn't use our smartphones.
