My son aged 7 years 3 months had a fall in 2020 from bed and got hurt in his lower back rightside to the back bone but no issues he has but his height is 120cm and weight is 21.5 so is this the normal weight and height for this age and he has a problem of
calcium as he gets fracture easily so what should be done and how to improve it.his
vitamin d 3 is also 13mg/d so can I please know that should be done next.
