But what's the difference between a kid having their own CD player and their own mp3 player?
Ha! To be honest, I have no idea what an MP3 player is, even. We have the one computer, no cell phones or other hand-held devices, and an old record/cassette/CD stereo. My kids have a CD player in their room. We tend to buy our CDs second-hand, but the bulk of them we borrow from the library. So I guess I'm just living in a different world from the rest of you! And it's a world where spending $100-$400 on an electronic device for a six-year-old to listen to music just wouldn't happen.
I see where you are coming from (yes, a bit of a different world - said in a nice way), but MP3 players are as cheap as $20, and songs can be found for free -- especially children's songs. So, it's likely a lot cheaper than the CD player your kids have in their room. The only difference is the size, making it portable. Also, something like an ipod shuffle is pretty hard to break, whereas, my kids would probably destroy the cd player tray or top part -- not even intentionally, just after a lot of use. Just like CD's get scratched and skip - but then, I think my kids are younger than yours and obviously not as gentle and careful (we are working on this, just being honest here).
Yes, iPods are definitely more durable than CDs. Do you know how many times I've run an mp3 player through my washer without knowing it was there? lol My iPod has gone through 5 times minimum in the time I've owned it, dh's player has gone through 11 times, and 7yo dd's has gone through once. LOL And, 3yo dd has chewed on all 3 players MANY times (mine has teeth marks on the clip, 7yo dd's has chew imprints on one corner, and dh's, well his has been spared so far somehow) and they still play. The same can't be said for the CDs that child has gotten hold of without my knowing it..................
