We all worry about our children as they grow and develop. You hear a lot about kids being overweight these days, but some parents struggle with underweight children.\nBefore worrying too much about your thin child, keep in mind that growth charts are based on averages. The focus should always be on helping your child stay healthy overall while instilling positive eating and exercise habits.\nWhat\u2019s a \u201cNormal\u201d Weight for Kids?\nLet\u2019s start with a look at the recommended weight for children.\nMost doctors use Body Mass Index or this growth chart from the Centers for Disease Control and Prevention (CDC). A child who falls below the 5th percentile is considered underweight.\nFor example, a 6-year-old who weighs about 36 or 37 pounds is in the 5th percentile. A 10-year-old who weighs 55 pounds falls into the 5th percentile. At the 5th percentile, thresholds for girls and boys are mostly the same.\nThese numbers do not account for height. Only your doctor can give you a better idea of where your child falls on these charts by including stature. If your child is underweight, talk to your doctor about your child\u2019s overall health and nutrition. Look for any nutritional deficiencies (anemia, lacking calcium or vitamin D), medication side effects, or unhealthy behaviors that may cause your child to not gain weight.\nRELATED:\u00a04 Tips for Teaching Kids to Eat Healthy\nWhat Can I Do to Help My Child Gain Weight?\nAlthough your first inclination may be to try to fatten up your child, remember that he or she will go through many growth spurts and changes over the years. Rather than focus on your child\u2019s size, which may create unhealthy feelings, encourage the whole family to develop healthy habits. Talk to your child about nutrition, and how eating the right foods makes our bodies stronger.\nHealthy Eating Habits for Kids\nFirst, take inventory of your child\u2019s current eating habits:\n\nWhat is he or she getting too much of? Too little of?\nWhat will he or she eat or not eat?\n\nThen develop an eating schedule based on your child\u2019s needs and habits. He or she may not be able to sit down and eat a lot at once. Instead, offer multiple, nutrient-dense snacks throughout the day with three modest-sized meals, for example.\n\nMake the calories your child consumes count:\n\nGo for nuts, seeds, cheese, fruit, and whole-grain bread or crackers for snacks.\nOffer strawberries with vanilla yogurt for dipping after school. Get more ideas with this guide to healthy after-school snack.\nSpread peanut butter on a whole-grain tortilla, top with banana slices and wrap it up for breakfast on the go.\nAt dinner, opt for lean meats or seafood with vegetables and whole grains.\nFor a picky eater, you may need to be a little sneakier. Does your child only eat macaroni and cheese? Try steaming and pureeing cauliflower and mixing it into the cheese sauce. Start with small amounts so he or she won\u2019t notice.\nBake your own muffins and cookies to include ingredients with more power, such as ground flax seed or wheat germ. This breakfast cookie recipe from The Sneaky Chef packs a healthy punch with sweet flavor. Mix in mini chocolate chips to make it even more of a treat.\n\nExercises for Kids\nAs you focus on food, don\u2019t overlook exercise. More movement can build your child\u2019s appetite and muscle mass. Take lessons, ride a bike, or play games in the yard. Make a point to help your child get at least 30 minutes of exercise each day.\nGenetics also play a role in being thin, and your child may have a higher-than-normal metabolism. By focusing on health, you\u2019ll help your child stay strong with a positive body image.
