this type of of legs is totally normal. no treatment is required except proper diet. kindly continue vitamin d supplements if you are not taking the child in sunlight. if proper diet is being given then there is no need to worry about any calcium supplement. the curved legs/ bend legs usually take a normal shape by two years to three years of age. if in doubt then meet the doctor.
