Children grow at different rates and have different appetites. The goal is not a perfect meal or a number on a scale. Focus on steady growth, enough energy for daily life, enjoyable family routines, and a broad pattern of nourishing foods.

When to Get Help Sooner

GET EMERGENCY MEDICAL CARE NOW

  • A child is very weak, confused, fainting repeatedly, severely dehydrated, unable to keep fluids down, or has another life-threatening emergency.

  • You are concerned that a child may be in immediate danger because of an eating disorder, intentional self-harm, or a severe reaction after eating. Call 911 if there is an immediate safety risk.

  • Rapid or unexplained weight loss; a child who is not drinking enough or urinating normally; repeated vomiting; severe or persistent abdominal pain; blood in vomit or stool; or signs of dehydration.

  • Food restriction, bingeing, vomiting, use of laxatives or diet products, fainting, intense fear of weight gain, excessive exercise, or body-image distress. These concerns need prompt, supportive medical assessment.

  • Poor weight gain, a major change in appetite or eating, choking or pain with swallowing, persistent diarrhea, or a family concern that growth is changing quickly.

How Growth Is Assessed

  • At well-child visits, clinicians look at height, weight, body mass index (BMI) for children age 2 and older, and the pattern over time. A single measurement rarely tells the whole story.

  • Children are compared with others of the same age and sex using growth charts. Puberty, family body type, illness, activity level, medicines, and muscle mass can all affect a measurement.

  • BMI is a screening tool, not a diagnosis or a judgment about a child. It is most useful when interpreted with the child's growth history, overall health, and family circumstances.

A Family Approach to Healthy Eating

The most sustainable changes are shared family routines. Avoid labeling a child as “good” or “bad” for eating, using food as a reward or punishment, or putting a child on a restrictive diet without professional guidance.

  • Offer regular meals and planned snacks. Adults decide what food is offered and when; children can listen to hunger and fullness and decide whether and how much to eat from what is offered.

  • Make water the usual drink. Offer milk or a nutritionally appropriate alternative as advised for the child's age and needs. Limit sugar-sweetened drinks and keep juice portions modest.

  • Build variety over time: vegetables and fruits, grains (often whole grains), protein foods, and dairy or alternatives. Include foods that fit the family's culture, budget, traditions, and preferences.

  • Eat together when possible and keep meals mostly screen-free. Conversation, routines, and adults modeling balanced eating are valuable.

  • Include movement, play, sleep, and stress support in the plan. Health is not determined by food alone.

Practical Steps for Common Concerns

“My child is not eating enough.”

  • Appetite often varies from day to day and may decrease when growth slows after infancy. Review the child's growth pattern rather than judging one meal or one day.

  • Offer familiar foods with a small amount of a new food. Do not pressure, bargain, or force a child to finish. Continue offering a variety over many meals.

  • Contact the child's healthcare professional if there is weight loss, poor growth, fatigue, pain, swallowing trouble, vomiting, or unusually limited eating.

“My child is gaining weight quickly.”

  • Start with family habits, not a diet for one child: regular meals, water, enjoyable activity, adequate sleep, and less screen-based eating.

  • Ask the child's healthcare professional to review the growth trend, medical history, medicines, stressors, food access, and whether a dietitian or other support would help.

  • Avoid weight teasing, shaming, or restrictive “crash” diets. These can harm health and make eating concerns worse.

“My teen is worried about weight or food.”

  • Listen calmly. Ask about eating patterns, exercise, mood, bullying, social media, and whether the teen feels safe. Focus on health, strength, energy, and support instead of appearance.

  • Seek prompt professional help for restrictive eating, purging, bingeing, use of diet pills or supplements, compulsive exercise, or emotional distress.

Vitamins, Supplements, and Diet Products

  • Most children who eat a varied diet do not need a long list of supplements. Some children do need specific vitamins or minerals because of age, diet, medical conditions, medicines, or laboratory findings.

  • Ask before using high-dose vitamins, herbal products, protein powders, “detox” products, weight-loss products, or sports supplements. Products sold without a prescription may not be appropriate or safe for children.

  • Keep vitamins and supplements locked away. Gummies can look like candy and can cause poisoning if a child eats too many.
