At Sawyer's school, they carry tote bags. Each class' tote bag is decorated according to who their teacher/room is. Sawyer's is decorated like a puppy and is really super-cute. Thankfully they are more geared to the itty bitty's size rather than the bag being as large as they are. But they ARE tote bags. Both straps SHOULD go on one shoulder. Not for Sawyer though. Nope. He likes to wear his like a packpack. And so we let him. Because it's cute. And really not worth the argument with a three year old.
