Should see a doctor: Average (50th percentile) weight for a 3 1/2 yo girl is 32.6 pounds, for a boy it is 33.6 pounds. Your child is very underweight and may be classified as "failure to thrive". There are several possible issues including insufficient calories in his/her diet, a chronic illness that is slowing growth, malabsorption problems (intestines not absorbing food properly), or a genetics problem.See a doctor.
