The shape and size of this backpack wouldn't make it good for papers or books, but is good for toys or diaper/toddler bag. The padded shoulder straps are great for carrying regular stuff, but not durable or thick for anything super-heavy.

I keep my daughters Leapster and all the cords, headphones, batteries, etc in this bag, and she can carry it all herself if we go on a trip to grandmas or something. It would also work well to keep a change of clothes (critical for potty trainers!) or a snack and toy. I like having something colorful and easy to spot, and that my 3-year-old can carry herself. She's so proud of her bag.

Note- we don't have any other Lalapaloosy stuff, but it's a cute bag whether or not your kid is into the show. The dolls creep me out, honestly.
