Sa experience ko sa students ko, it's better na nagsusumbong sa akin ang mga nabubully na kids. Para aware ang teacher na may ganung nangyayari. Tell him to tell the teacher instead na magalit sya. Talk to the teacher also, nicely. Tell the teacher that bullying is happening. the teacher should do something about it. At home naman, you should just reinforce ang self -esteem nya by affirming his strengths. Doble effort. Pero if things get worse, introduce him to a sport. It's a great way to help him lose weight and gain confidence. -- i was a chubby kid and a chubby adult. I know how it feels.
