There is no direct correlation between children’s thick legs and height, so the theory that children with thick legs will not grow taller is wrong. The child’s height is affected by heredity, environment, nutrition, psychological state, disease and other related factors, but not related to the length and thickness of the legs. Before the age of 12, the proportion of the lower limbs in the whole body is not very large, and at the age of 12, the proportion of the upper body and the lower body are equal, and the proportion of the legs is gradually increased after the age of 12. So if the baby simply exists leg thick, parents worry too much about height is unnecessary, only need to pay attention to nutrition, mental health, more outdoor activities can be.
