My kid turned 3 recently, and, as a present, I gave them a kid-friendly music player pre-loaded with songs. The speaker is shockingly good, and turning the volume the whole way up can make the music quite loud.
My mother-in-law is Skyping with my sister-in-law, and my kid keeps slowly turning up the music on the player like they're playing a celebrity off-stage at the Oscar's. 😂 😂 😂
