Santa brings everything that you need including batteries, games, etc... but he can't do everything. For a really young child, I can see why he might take care of that detail, but for older kids, including my 8 year old, they have to do the charging, loading themselves! (It isn't like that will be his only present so I am thinking he won't mind!)
Santa leaves everything set up here -Santa wouldnt' give my child a bike not put together - so to me its the same thing.
SO I've taken her nano & loaded only 6 tunes so far - hope to get more on there tonight - the computer is in her room! I know what music she likes - but I'm not using the whole $50 itune card - so she can download some herself...with me beside her - I'm EXTREMELY picky on music so I must hear all the songs.
