Hi there, My name is kenny, i am 16 i am 155 cm tall! my father is 178cm i have been to the doctors, and questioned them about my height, they said maybe i do not have enough vitamin D inside my body, i dont think i have had my growth spurt. i am really worried, because my friends and peers around me are probably 10-15cms taller. can you please help me? ive been taking vitamin D for about almost a month. but not seen any result of growth sadly. will i have my growth spurt? Yours truly Kenny!
