I bought this backpack for my almost-three-year-old.  She loves it!  She likes the independence it gives her.  She can put her mommy-approved items in her own little bag, carry it around, and get into when she wants.  At the moment it's holding a few sheets of 8X8 scrapbook paper, a pack of crayons, her mini sock monkey, her bathing suit and her sunglasses.  It will hold much more.  It would fit a change of clothes and a drink too.  Perfect size. Very soft and lightweight but durable. Button-adjustable shoulder straps.  Couldn't be happier.  I actaully just placed an order for another one for a friend who's about to have a baby becuase it would be the perfect size to take essentials for a quick trip to the store.
