The legs of a newborn baby look a little bent and not very straight, which is generally a normal physiological phenomenon. This is due to the fact that before the baby is born in the mother’s womb is a relatively small space, and the child remains mostly in a flexed state. So after the baby is born, the legs will look a little bent, and there will often be hooked legs. Parents do not have to worry too much, as the child grows older, generally after six months, the legs will gradually become straight. It is recommended that in daily life, the mother should eat a balanced and reasonable diet and take in enough nutrition. After the child is six months old, the child should gradually increase the supplementary food, but also help the child’s healthy growth.
