Hi, Take fruits which can be fine for two days. You can make khichdi, which will atleast take care of his one day meal. You can carry porridge. But, I think this will all be good to be given for one day since weather too have changes and you can not store this food for more than one day. And wherever you go, I think you can conveniently get rice and dahi that you can feed the baby with out any risk of him getting upset tummy that babies get if they eat out at this age.
You can take yogurt, boiled potatoes, banana, bread, curd, rice, biscuit, boiled egg. http://wholesomebabyfood.momtastic.com/travelwithhomemadebabyfood.htm
