i have the same issue. i have one daughter, who was/is of a normal weight, played sports, etc. however, my youngest started putting on weight at about 6 yrs. of age. she's 17, almost 18 now, and it's always been a struggle for her. we found out why. she has hypothyroidism. not only did she get the genes from her father, but she has a real and phsysical condition that adds to her weight. her calories do not metabloize and burn as they should.

i would have her tested...especially with the other child being of normal weight in the same household. it makes sense yes? also, hypothryroidism causes the children to be sluggish (appear bored), have no energy (again appear bored), etc, etc, etc.

i blamed myself as well. as i said, there are two children in that house and one has no weight problem at all. it sounds like there's more going on. dr's can be cruel too. we dealt with one once. i had my family dr call her. he was ticked.

now is the time to invesitigate the physical and emotional aspects of this. i would start with the physical. there may be no "fault" here.

good luck,
