Keeping a pregnancy journal with spaces to record your menus may also be invaluable to your pediatrician. If you madly consume a jar of pickles in one sitting, it's easy to explain your upset stomach. Your pediatrician may notice that you're not eating enough protein foods or are not getting sufficient calcium with your diet and can make good recommendations to keep you and your baby as healthy as possible. Your child may also someday get a kick out of learning that you ate fish every other day for nine months.
