Hi, My daughter is 16 months old and still she is not able to walk even stad by her own however her only source of food is mother milk despite of our all efforts she doesn't have any other food supplement even milk juices. I have seen her to doc and we have done her wrist xray and then we came to knoe that she had rickets but not severe one and doc advised to gv her vitamin D and calcium as well.  I am very tensed please advice. Thanks Azad negi
