kids in the promo

I was wondering if the kid who Archana is carrying is sachin jr or the other one standing next to the ganpathi in the promo
Since if teh show takes a leap of 5 years sachin jr should be about 6 years or close to 7 years old which loks like the other kid who is standing next to Archana and teh kid she is holding is hers and Manavs
Can anyone please clarify that !

SO basically all teh kids should have grown up pretty much !!
I hope they stick to this calculation since the leap of 5 years does mean a lot of changes in terms of kids and their parents and upbringing

Opps yes 4 years leap .. I was confused thinking its 5 years
Thanks..
So how come savita allows Manav and Archana to part from her grandson
I read in TB article that Archana will give her child to Varsha..

So is this to give a new storyline and then something later in the life they have misunderstanding or something
