Hello experts my son 4 and half month baby. His leg is bend from knee to toe . is this comes straight naturally . I m worried so much

A. it is normal at this age 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.
