you cant grow any more ALTHOUGH you can get taller. i only know one way though. sorry. so here it is- do stretches. for example, you everyday try to touch your toes either standing up or sitting down, and many other stretches. some work for knees, and some work for back. trust me , this works (with some exeptions such as your back is already maximum stretched out or some thing etc) and dont pay attention to the people in the other comments...theyre wrong.
You can't really increase your height. The average person usually stops growing between the ages of 14-16, so sorry, you are going to stay that height. You can wear heels! You see, I can't wear heels because I am super tall. You are lucky. It doesn't matter how small you are, what matters is how big your heart is :) Hope I helped
well, this could of happened because when you sit down, you slouch, so your spine doesn't let you grow properly. If you sit up straight from now on, you might have a chance. A small change can make a big difference.
There is an exercise that elongates your back that can make you about 1-2 cm taller. I don't know if it is such a healthy exercise because it causes your back to hack out once a day. You have to strap yourself to a contraption almost like a wheel and then let somebody turn it upside down to let your back hack out. Lie like that for a while and then let it turn back around.
