My 16 Year Old Daughter Is Only 56 Inches (about 142 Cm) In Height. I See Her Worry Too Much About It. Can Anybody Tell Me Something That I Can Tell Her To Soothe Her Worries Or Just Suggest How Can She Increase Her Height In An Easy, Natural Way?

One cannot increase their size of height. You can lose weight, add weight, you can change hair colour and even eye colour (with coloured contacts) but unfortunately, it's not possible to change height.

It is possible of course to emphasise her size less by the way that she dressed, she can wear boots and hats, which add height at both ends, potentially, about two extra inches, but really this is something that she needs to learn to cope with.
Under exceptional and optimum conditions, her height can still change, although she has already passed the time when her greatest growth spurts will occur.

Instead, you should focus her on other things, eating healthy, exercising, doing her school work, making and sustaining great friendships, there are a lot of tall people in the world and a lot of short people in the world, but many more unhappy people, building her self confidence and working on maintain and sustaining a fulfilled life will do more for her than a few extra inches or cms.

Dynamite things come in small packages! She may or may not become tall but the good thing is the fact that guys usually prefer girls who are shorter than them. They do not like to look up to their girlfriends. I am short too but I love the fact that I am a 'mini-wonder.' I do not have to look at people if I do not want to. When they complain that I never look up at them, I can always escape by saying that looking at them gives me a neck-ache! Your daughter will get used to her height and will be okay with it. Teenagers always have problems with the way they look and they do eventually grow out of it. It is all part of being a girl.
