A. It should be about 10 kgs by the age of 12 months of the year child is little underweight over here I would advise you to go ahead with giving more of proteins Best diet to the child because that really helps a lot and overall weight gain and growth of the child and if needed you can consult a nutrition expert for a proper diet plan
