Books and other teaching materials may be hard to come by, so be sure to take along any books that you may want for teaching and teacher training, some children’s books in English if you anticipate working with children, and some school supplies.
The Peace Corps Medical Office provides basic medical supplies such as acetaminophen, ibuprofen, sunscreen, insect repellant, bandages, etc., so you don’t have to worry about bringing those kinds of items or trying to find them in country. However, certain feminine hygiene products may be hard to find or very expensive.
Some foods (e.g. chocolate, butter) may be difficult to find or prohibitively expensive, depending on your country and site, so you may want to pack a supply of your favorite snack or cooking ingredient!
