Lots of reasons. Kids drop things, lose things and tend to have less general awareness than adults. I can't count how many times I've dropped my wireless earbud case and had the earbuds pop out and the case close. It's easy to imagine a kid losing one, both, or the entire set including case. Wired headphones are tethered to the device when plugged in and easier to replace. Wireless earbuds turn the setup into 4 discrete items that can be lost (L, L, case, device). Device+wired headphones is less to think about.
