12 year old girls under 69 lbs or over 123 lbs and 12 year old boys who weigh less than 67 lbs or more than 119 lbs may want to consult with a doctor. The American Academy of Pediatrics recommends that children who's weight is outside the 5th or 85th percentiles seek professional advice to determine if further evaluation is needed2.
As children approach adolescence at the age of 12, they experience growth spurts and various physical changes. The average weight for a 12-year-old typically falls around 90 lbs for boys and 92 lbs for girls based on CDC growth charts1. During this time, girls may enter puberty earlier than boys, which can lead to differences in weight and height between genders. While it's natural for children to gain weight during growth phases, fostering a supportive and non-judgmental environment can help them develop a healthy relationship with their bodies.
