clearly you need to check in with your pediatrician and make certain that your daughter does not have a host of metabolic conditions that could be contributing to her weight gain. in addition look at your family history (yours and the father of your child). if there's a strong family history of obesity she may have inherited the genetic tendency to gain weight. that being said she can't gain weight without overeating relative to her needs. once she's checked out for medical problems you need to request a pediatric dietitian referral and work out a plan that will get results. she's clearly overeating relative to her needs. you'll experiment and refine her dietary intake. she'll also need you as parents to mentor her with your good nutrition habits. she needs a healthy lifestyle-friendly environment to achieve her goals.
