the key for growth at this age is looking at her growth over time. has her growth been steady since birth but at lower percentiles or has it dropped recently? red flags for growth are when they cross 2 percentile lines either up or down. also doctors should be using the world health organization growth charts for children under 2. if you pediatrician is using the cdc ones it could give you daughter a lower reading. lastly i highly recommend seeing a pediatric dietitian. he/she can assess what/when/how your child is eating and provide recommendations. typical reasons for groth issues include difficulty transitioning to solid food excessive juice/milk stressful feeding and a low fat/low calorie diet. children under 2 need more fat so that is an important consideration when deciding what foods to offer. also timing and feeding interactions can make a big difference in how well a child eats. you can get a referral through your doctor to a outpatient program at a children's hospital or find a dietitian that specializes in pediatrics by visiting eatright. org. once you get some answers you can rest easy knowing you are doing all you can do.
we are having some weight gain and growth issues with our 17 month old. my daughter stella is 17 months old. she is only 18 lbs and not growing well. she is in the "less than 2nd %" on both height and weight. we have been to several doctors and have had several tests done and luckily everything has come back fine. stella loves to eat! she can eat a kids meal and 10 minutes later be asking for a snack. with all the food she eats she should be an obese baby. she is doing great developmentally. anyone with some advice on other tests please let me know.
