Our son was 12 months old, with 2 bottom teeth, and the top 2 trying to break through. He had been eating "mashed meat and vegetables" at the orphanage, so we stuck to mashed veggies - the chunkier baby food in jars we bought there, and whatever we could mash ourselves with limited means at the hotel. Also formula and rice cereal. We also had lots of plain Cheerios, which he loved. He ate and ate and ate! We also brought the bowls w/lids and spoons and bought most of the food there.
Good luck - it's quite an adventure.
Best advice - try to stick to what the child is used to while in country. The diaper issues from unfamiliar food are - shall we say - not pleasant!
