My son just turned 2 and I wanted to get him a backpack so I could lose carrying the diaper bag around. I mean he will be potty trained in no time right...lol.  Anyways - he absolutely loves it and carrys it all by himself everywhere we go.  The side pocket fits his sippy cup perfectly, the front flap holds some of his cars or snacks he likes to bring, while the main part holds his diapers/wipes (for now), along with his blankets and stuffed animals he won't leave home without!  I love the bright colors as well!  Great buy for the money!
