They had a son?

Hey guys,

I'm so confused! I remember watching an episode where Naira & Kartik were told that they would only ever have one daughter... and now they have a son? I know they had a daughter the first time Naira was pregnant, but it's making me wonder... is this even their son? Like did she ever give birth to her own child or is he adopted or something? 

What are your thoughts?

Naira was pregnant before the leap so Kairav is her own son. Don't pay to much attention to pandit words they don't always come true. Also I know in hindi serials there is a lot of importance given to such pandits but I guess creatives have decided to ignore that small scene and give Kaira a son.
