Thank you for your query.
There is reason to worry. Rickets
generally does not manifest before birth.Rickets should heal after Vit D injections except the resistant varieties. I think there is some other cause for the short stature which needs a proper diagnosis before treatment. Short stature before birth is usually genetic or metabolic.Please consult a paediatric endocrinologist
for your child's problems.Hope this answers your query.Have a nice day
