my daughter is 7 month old.is bow leg normal or serious. how to prevent this problems

A. this type of of legs is totally normal. no treatment is required except proper dietc. kindly continue vitamin d supplements if you are not taking the child in sunlight. if proper diet is beingc 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.
