Breadsticks, grapes (a bit sticky and runny but keeps IzzyMouse occupied for ages), pitta bread pre-cut into sticks and spread with your LO's filling of choice. Muesli bars, bought or home-fashioned as is your want. Those weird not-cheesy-wotsit organic thingies. We love moon biscuits but find they're too messy for out and about. IzzyMouse turns them into a face pack in seconds.
