Thanks for update.
@Esha, true Sanchi character (for that matter almost all Shakhers are not properly developed) has not developed properly. She does not even look the antagonist, she is devoid of all human qualities. Even evil people behave like humans- nobody is evil for the sake of being evil - she does not love even her mother - she does not like happiness of even her own family. Even evil people take care about their own life - but Sanchi destroyed even her own life and is still on the same path.
Jagya's son is cute and we cannot expect creatives to bring some actual premature baby - but they could have taken somewhat underweight baby to make it look more close to premature baby. It is good that they do not show young babies - like Bhairvi more often - but they should add some dialogues - like Gahna may mention that Bhairvi is sleeping - to explain her absence from the important function - to make it clear that they have not forgotten her altogether.
I would have preferred a normal pregnancy and delivery under normal circumstances for Ganga, but as they say - All is well that ends well - so am happy that the mother and child are safe.
