Snacks may be helpful to have during the visit, as long as they don't interfere with the exam. Also bring a stuffed animal, blanket, pacifier, book or favorite toy for play and comfort while waiting and during the exam. Include books about doctor and clinic visits in your child's regular reading. This can be most helpful before a visit, but include them in general reading because visits for sickness or injury are usually unplanned and leave little time for preparation. The best books suggest that visits are not fun, and may be scary and even hurt, but show how kids can successfully handle them.
Some books are quite funny.
You can practice with your child such things as opening your mouth wide, breathing through your mouth, and holding still. It is often the unfamiliar that is frightening, and you can make a personal scrapbook or picture book to remind your child about past visits. This can be especially helpful for children with health problems and frequent doctor or clinic visits. Always be honest with your child about what to expect. Use simple language and be as specific as possible.
