I think there was a recent post about this but I can't find it. What snacks are good to take into the parks (I have a 2 1/2 year old and a 7 month old who eats only Cheerios for now as snacks). And how do I package them for the trip? We are traveling by plane. Do I take them as a carry-on or check it in? I've been reading some tips and it sounds good to take the snacks in an extra bag that I can use later for souveniers but I'm not sure whether I should check it in or carry it on and I'm not sure what will not burst or crumble. Help please I leave in three days!! Thanks you so much.
