As middle graders mature, their bodies start changing in uncontrollable ways. Examples: acne, growth spurts, facial hair. This often makes them feel awkward about their appearance.
Suggestions:
When your child makes negative comments about his appearance, listen to what he says. Try to avoid immediately reassuring him. Instead, make comments that prompt him to describe his feelings. Example: "That must be really tough." This encourages him to open up about his emotions.
Make your comments in a matter-of-fact tone. Middle graders are likely to find joking and teasing hurtful, even if you're just trying to be funny.
Talk about how you felt when you were his age. If he doesn't believe you, pull out old photos. He will quickly see that you're telling the truth. Gently explain that his friends probably feel the same way about their bodies. Let him know that these changes will be less and less noticeable as he gets older.
