the one thing i've noticed about my ciao ciao since i got it yesterday is that the hardware clanging together makes quite a ruckus. it's comfortable to wear though, but i guess even though i'm petite i'm not picky about sizes and styles 'cause i carry a cucciolo to school.
i think like the bambino/bambinone vs the dolce the stellina would hold thicker items, but the ciao ciao would hold longer items. the ciao seems pretty small to me though.
