my baby is 2 yr old.her leg is slightly bent below the knee. how to get a straight leg? is there any problem?

A. this type of of legs is totally normal. no treatment is required except properf 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 curvedf legs/ bend legs usually take a normal shape by two years to three years of age. if in doubt then meet the doctor.
