My niece had this problem as an infant. Her pediatrician did not recommend anything to her parents or suggest a diagnosis. My niece has been (shortly after birth)and is now (age 8 years) very obese. We have no history of obesity in our family and have always suspected that there is more to her obesity than food intake. I would suggest looking into this and getting a second or third opinion from a specialist.
