SO much room!
I bought this bag to use as a more stylish diaper backpack (and also to use beyond babies..). We currently cloth diaper and will soon have a 2nd baby who will also be in cloth diapers. There is SO. MUCH. ROOM. It doesn't even look like it would have that much room, but you open it up and can fit cloth diapers, clothes, snacks, toys and even things for me! Looking forward to using it more as the baby comes and beyond kids.
