I was never the "good job" kind of mom. My two sons didn't get standing ovations for doing ordinary party tricks like learning to use the potty, eating broccoli or making their beds. Nope, I never subscribed to the theory that "good job" parenting would minimize their risk of becoming future psychopaths.
Talk to your son about his body. Give him the vocabulary that he needs to communicate how he feels about himself. Teach him that it's normal to think about his appearance. Teach him that being a boy doesn't take away his right to have feelings about his body. Don't assume that you can talk about your son's body any differently than you talk about your daughter's.
I sometimes wonder if I was properly prepared for having five kids, four of whom are little boys. After all, no one handed me the instructions manual that explained what makes boys tick! So, I've decided to write the Cole's Notes version, just for you! Share it if you know someone who also never received the manual!
