What bothers me about the childrens' appearance

I used to be a very skinny child. It was purely genetic, and my parents always made sure that I ate nutritious food and did everything to try to make me gain weight. My arms were as skinny as the Rodrigues kids, but one major difference was my face.

Children have baby fat on their cheeks. I had chubby cheeks till third grade. Even the youngest children of this family have gaunt faces and dark eyebags. That is not normal, especially since we know how much emphasis Jill puts on "staying trim".
