Infants
Newborns typically lose about 5 to 10 percent of their body weight during the first week but should start gaining weight by the end of the second week. Infants grow at an astonishing rate, and by four to six months, their birth weight usually doubles. Growth spurts can occur around the second week and between the third and sixth weeks. You may notice that your baby is hungrier during these growth spurts. Feed them more to meet their additional caloric needs. An infant’s weight typically triples by their first birthday.
Toddlers and Preschoolers
You might notice that your preschooler has a decreased appetite. This is normal and can be a sign of slower growth. Continue to provide healthy foods for meals and snacks, and don’t worry if your preschooler occasionally refuses to eat.
School-Aged Children
BMI (Body Mass Index) is a calculation based on your child’s weight and height that measures body fat. The CDC provides four categories of weight status based on BMI percentiles:
- BMI between the 5th and 85th percentiles is considered normal weight.
- Below the 5th percentile indicates underweight.
- Between the 85th and 95th percentiles indicates overweight. Growth charts can also be used to track your child’s weight. Your child should remain in the same percentile on the growth chart as they age. Most children between the ages of 2 and 10 grow at a relatively steady rate.
Adolescents
Between the ages of 9 and 15, your child will experience another growth spurt, signaling puberty. This growth spurt can last from two to five years. Appropriate weight for adolescents depends on their height and the timing of their growth spurt.
Maintaining a healthy weight is crucial for your child’s overall well-being and development. Regular check-ups with your pediatrician can help ensure that your child’s growth remains on track and address any concerns you may have.
