I tried picking up dd's school bag the other morning and cannot believe how just heavy it was. She's in yr 10. There were 4 text books, the same number of folders, pencil case, art stuff, lunch, ipod, phone and make-up. She says she needs it all. She has a locker but WILL NOT use it as apparently it is in an awkward place and smells, so carries all this around all day. She's not exactly a strapping lass & I'm really worried she's going to have problems with back/neck/shoulders. what to do?
