4 years Nutrition Food intake and preferences may vary from day to day, but continue to offer your child 3 meals and 2-3 snacks a day of healthy foods. Your child will eat when he is hungry and will not lose weight from periodically refusing to eat. Limit high fat or low nutrient foods and beverages (candy, chips, pop); it is often less tempting to just avoid having them in the house at all except for special treats. Milk is still recommended (about 2 cups a day), but yogurt and calcium-fortified orange juice are appropriate substitutes for children who do not care for milk. Mealtime is often a very active, sometimes giddy, time of day. Encourage control but also happy family time, as this may be the only time all family members are together at one time. This is a good age to enlist the help of children for mealtime "jobs" and in safe help with food preparation. Keep a copy of the USDA Food Pyramid on your refrigerator so you can help your child learn the value of nutritious eating. You are still your child's primary tooth brusher. Brush at least twice a day with a small amount of toothpaste. Dental visits are recommended every 6 months. Wellness Visits Most children sleep 8-12 hours a night. Naps sometimes become "rest periods" at this age but still allow both the child and caregiver to have a break. Try to make bedtime pleasant and consistent (even if an older sibling has a later bedtime). Sleep Remember that all children have accidents, even after successful toilet training. Help your child learn to clean up after himself and listen more closely to his own body's signals. Nighttime wetting may take longer to master, as this is a developmental (versus behavioral) skill and the timing can also be inherited. Try to remain positive and not focus on the issue. It should resolve with time. If your child reaches 7-8 years of age or becomes bothered by it, consult your health care provider. Elimination Minnesota law requires all children to be in appropriately sized, federally approved car restraints until they are age 4 and 40 pounds. After that, your child will continue be safer in a booster (now approved up to 80+ pounds) and all children under 12 should ride in the back seat. Make sure the seatbelt fits properly, and teach by your own good example. Discuss "good" and "bad" touch and appropriate contact with strangers. Use sunscreen (at least SPF 15) during all outdoor daytime activity. Teach respect and caution around all animals (even your own). If you have a gun, lock it out of sight and lock the ammunition separately. Enforce helmets (without exception) for biking, scooters, skateboards, and in-line skating. Never leave your child unattended near water, even if he can swim. Wear life vests when boating (it's a Minnesota law) or in deep water. Continue to update your childproofing. Choking, burns, injuries, and poisonings still occur at alarming rates at this age. Keep all medications and toxic household products in a locked cabinet and make sure all have working safety caps. We also recommend that you keep the Poison Control Center (800-222-1222) phone number handy next to all of your home phones and programmed into your cell phone. Remember that children imitate parents, so avoid taking medications in front of your child. Continue to monitor your child's exposure to second-hand smoke. Safety Children at this age are often eager to please and are very proud of their knowledge and skills. They enjoy having parents (and occasionally siblings) participate in games and school preparation challenges (counting, ABC's, songs, crafts). Most parents also start to realize that children become more independent and sometimes choose friends over family for certain activities! Encourage more of that independence by having your child practice routine self-care skills (choosing clothes, getting dressed, washing the face, brushing teeth and hair). Discipline can become more of an issue, with many children openly disobeying rules. Teach acceptable behavior by setting limits and dealing with misbehavior promptly and fairly. Daily and weekly family time helps cohesiveness and communication. We look forward to seeing your child again at age FIVE, the infamous pre-kindergarten visit. The DTaP, Polio, MMR, and Varicella (Chicken Pox) vaccine boosters will be due, so prepare your child the way you think is best. Please try to be at least 10 minutes early for all scheduled well-child visits.

12, 13 years (female) Nutrition Try to eat 3 healthy meals a day and limit the "junk" so your body can do its' best work (in school, sports, etc.). Your need for calcium increases to 3-4 servings a day (more than the Food Pyramid suggests) because your bones are soon going to be at their peak of strengthening and growth. Milk, yogurt, or calcium-fortified orange juice are good choices. Also, increase your iron (2-3 foods a day of iron-fortified cereal, meat, eggs, or green leafy vegetables). Your eating habits now will always pay you back later, for better or worse. Many adults wish they had known to eat better when they were younger. Some illnesses could have been prevented by eating more fiber (fruits, vegetables, breads, cereals). Try not to get into habits that will be tough to break, such as eating on the run or in front of the TV. And as your life gets busier, try to eat with your family once a day. If you are unhappy with your body's appearance or performance, take a good look at your eating and see what you could change. If you eat well, drink plenty of water, and exercise regularly, your body will naturally grow at its' own pace. If you are concerned about your size, please talk to your health care provider. Wellness Visits If you want your teeth and gums to be healthy your entire lifetime, take care of them now. Brush well 2-3 times a day and see your dentist 2 times a year. Teeth Your sleep needs may increase as your growth increases. Try to go to bed earlier instead of sleeping in; getting up late can alter your normal body rhythm and make you even more tired during the day and sleepless at night. Also, try not to save all of your "think time" for bedtime — it often delays falling asleep. Sleep Always wear your seatbelt in the car and your helmet when biking or in- line skating, even if no one else does. We see permanent, life-changing injuries resulting from simple accidents, and NO ONE thought it would happen to them. Wear sunscreen if you are outside. A great tan is not worth cancer. Wear your life jacket if boating or near deep water, even if you swim well. Never take medicine (including vitamins) without knowing your dose. Evaluate what it will take to give your body the best. Make the decision now not to smoke, take drugs, drink alcohol, or have sex. Practice what you would say if someone pressured you. It only takes one mistake to change your life forever. If you have questions about sex, HIV or AIDS, drugs, alcohol, or tobacco, please ask your mom, dad, or doctor or nurse practitioner. Introduce your friends to your family, negotiate your curfew times reasonably, and expect that your parents will want to know where you are. If you are in sports, make sure the playing areas are kept up well, and all protective equipment fits and is in good shape. Never share head gear. Safety Your friends and school activities are important, but try to participate in a "family" event at least once a week, and sit and talk with your mom or dad a little every day. You may not always agree on things (such as household jobs, curfew, or friends) but talking about your differences helps you respect and understand each other better. And remember to take some "free time" just for yourself every day. Family Many girls notice the body changes of "puberty" happening now (they can start anywhere between ages 8-14). These include fast height growth, breast development, armpit and pubic hair, body odor, acne, and interest in boys. Most girls start their periods between ages 10-16 (average 12-13). In regards to acne, the best prevention and treatment is staying healthy on the inside (eating well, drinking water, getting sleep and exercise). Wash your face no more than 2 times a day with your hands and very mild soap and limit make-up. Boys usually start puberty by ages 12-14, with their growth spurt at ages 13-16. Body changes can make people excited, nervous, or embarrassed, so respect other people's privacy. If you have questions or concerns about your health, body changes or sexuality, please talk with your mom or dad or your health care provider here. There are also many good books available on these topics. We look forward to seeing you again for a check-up next year!
