Babies usually triple their birth weight the first year. That's why nutritious and safely handled food, served in an age-appropriate way, is so important. Being aware of safe food handling practices and potential feeding dangers are the best ways to protect your family from food illnesses and accidents, while also giving your child a healthy start on development and growth. Here are a few important tips and reminders.

1. Wash Hands. It's important to wash your hands before preparing food or beverages, especially when feeding babies. According to a Penn State University study of mothers with infants less than 4 months old many moms said they routinely forget to wash their hands after changing baby's diaper, and using the bathroom. Not washing hands could result in infant diarrhea from the bacteria transferred while engaging in these activities.

2. Handle Bottles Carefully. Although some babies will drink a bottle straight from the refrigerator, the American Academy of Pediatrics (AAP) advises most babies prefer milk warmed to room temperature. Warm the bottle by holding it under a running hot-water faucet or putting it in a bowl of hot water for a few minutes. Shake well and test milk temperature to make sure it's not too hot before feeding. Microwaves can heat unevenly. Children's mouths and throats can be severely burned by bottles heated in the microwave. Always discard leftover milk in bottle to reduce the growth of harmful bacteria.

3. Cow's Milk. Avoid serving regular cow's milk until infants are 1-year-old. Before then, infants may experience an allergic reaction, stomachache and low blood iron. When you begin serving regular cow's milk, serve whole milk. Do not switch to lower fat milk until the baby's doctor recommends this change usually around age 2.

4. Mixing Cereal and Formula in the Bottle. Do not serve cereal mixed with formula from a bottle. Many think this practice helps babies sleep better through the night, however there is no evidence of this. Plus, there is a possibility of a baby choking.

5. Hold Baby When Bottle-Feeding. Babies who are put to bed with a bottle are more likely to have cavities. This practice also increases the potential of choking.

6. Limit Juice. Serve only 100 percent juice and in small quantities so it doesn't interfere with the infant eating other nutritious foods. AAP recommends giving juice diluted with water only to infants who are approximately 6 months or older and who can drink from a cup. AAP recommends offering no more than a TOTAL of 4 to 6 ounces of juice a day to infants. (Source: American Academy of Pediatrics Committee on Nutrition)

7. Avoid Honey And Corn Syrup. Do not serve infants honey or corn syrup during the first year of life. These foods may contain botulism spores that could cause illness or death in infants.

8. Food Introductions. When introducing new foods, try only one at a time, and start with single-ingredient foods. Avoid serving mixed ingredient foods until each food has been given separately. Begin by serving about 1 to 2 tablespoons and then increase the amount as baby wants more. Wait at least 3 days before trying another new food so you can tell if there are any adverse reactions.

Iron-fortified rice cereal is usually the first food offered, as this is easily digested. It's frequently recommended to continue fortified baby cereal through the first year of life. Remember your baby will still be receiving the majority of nutrition from breast milk or formula during the first year.

9. Serve Solids Safely. Transfer an amount you feel baby will eat from the baby food jar to a dish. Throw away any food left uneaten in the dish. Avoid feeding directly from the baby food jar. Bacteria from a baby's mouth can grow and multiply in the food before it is served again. Use refrigerated jarred baby foods within 1 to 2 days after opening.

Once opened, do not leave baby food solids or liquids (breast milk or formula) at room temperature for more than 2 hours. Bacteria can grow to harmful levels when food is left out longer than this.

10. Choking Hazards. Avoid serving foods that may choke an infant, such as nuts and seeds, raw carrots and celery, whole kernel corn, raisins, large chunks of meat or cheese, popcorn, chips, pretzels, grapes, whole berries, cherries, unpeeled fruits and vegetables, hard candies, pickles, hot dogs, marshmallows (regular or miniature), and peanut butter. In general, avoid foods that are round and firm, sticky and chewy or cut in large chunks.

As infants grow into toddlers, they can begin eating the foods above, if cut into small pieces. Most pediatricians advise foods should be no larger than 1/4 inch for toddlers and 1/2 inch for preschoolers.
