Keep all nuts away from children under the age of five. Cut apples and carrots into small pieces. Olives must be pitted. Skip snacks like lollipops, popcorn, raisins, peanut brittle, marshmallows, toffee, gumdrops and M&Ms. Dried fruits are nutritious, but may be highly caloric if sweetened. They are also highly susceptible to infestation of small insects, and detailed cleaning guides are available on the internet.
