Babies come in all shapes and sizes. If a baby's weight is in a lower - or higher - percentile, this does not necessarily signal a problem with their growth or physical development. A weight chart can help you track your baby's growth, as steady weight gain is a sign that your baby is healthy and feeding well.

Adolescent girls typically experience dramatic changes in weight, bone composition, height, and body fat distribution - especially through their pubescent years.

However, it is important to keep in mind that many children in this age group are experiencing a pubertal growth spurt, and it may appear they are overweight (by weight-for-age) when, in fact; they are just tall.

During this period, it is possible to gain and lose weight rapidly and add inches to their height - seemingly overnight.

Every baby, child, and teenager is different in how they mature and grow during their teen years. Dieting for teens is not recommended, as quite often you will find they will simply "grow out" of their "baby fat" as they mature into young adults. Your pediatrician or family physician is the best person to consult if you are worried about your child's height-to-weight ratio, as a doctor can use a medical growth chart to keep track of their progress as they mature.
