DS getting to that age when too long in a pram queuing at the bank or highchair / lap at a cafe and he's getting grouchy. DD at the same age was happily preoccupied for a while with a cruskit or rusk and I loved both as they'd keep for a while and were easy to chuck a couple in the nappy bag on the way out the door.

Problem is, they both contain dairy and DS is intolerant. Anyone know of an alternative - ideally no/low salt, no/low sugar and additive-free?

TIA
