please, i preach to all that before you talk about anything, do some research first or at least know what your talking about.

having man boobs at young age is not much of a problem. as long as he is actively playing sports because this is due to the hormonal change and the amount of processed food d kid is taking. as he starts to mature or reach puberty, the testosterone levels will shoot up as well giving him a much masculine figure and all along with a groggy voice and stuff. of course, unless he is EXTREMELY fat. even so, it does happens.
