When we see in writing, adults calling a size 12 or maybe a size 14 high school girl "bigger", we no longer need to wonder why our children have eating disorders.
Perhaps we should focus on the root cause here, which might be the fact that the uniforms are made for cheering and not the great gymnastics we have gotten to see!
Our kids have enough problems without us putting additional pressures on them for their size and their expressions.
Contact the principal or the coach if you see something that concerns you. Let our kids be kids.
