Junior,

My DD8 is in 4th grade. She is the youngest as well as the smallest in her class. She is even smaller than her reading buddy from the 1st grade. Last month, she said it was kind of embarassing that she is the smallest in her grade. I sat down with her and explain to her about genetics (me and my DW are short) and nutrition. She is at peace now (we made her feel proud that although she is the smallest in size, she is the smartest in class and all those stories like David and Goliah helps too) but she started eating more vege and protein. She is now taking her multivitamin on her own too.

Boys are a little different especially if he is interested in organized sports.
