help with new ipod

[needsomesleep]

Hi everyone i just bought my son a new ipod nano and i was wondering if you have to go through i-tunes to get songs off of a cd we had already burned.

the reason i ask is when we go through itunes and put the songs on the ipod and then i delete them from my i-tunes the next time he adds more songs to the ipod it deletes the songs that are no longer in my i-tunes. i hope this makes sense and i hope someone can help me. thanks
