I have no problem with Asmi who is doing full justice to CA but CA is the most annoying child in this show. Her relationship with Vannnu and Kavya both is more interesting than her relationship with Maaya,Maa and Anuj. She would make a perfect Vanya kid.
Usually children of leads are very quirky and fun like Savi and Kairav. Even characters who become negative later like Vinayak are more fun. But this kid CA is shown as mahaan and her only 2 quirks Yeah!Yeah! And Kanha Bro are either loud or forgettable. Plus her so called adopted Maa is 1000 times quirky than her. Isse acha RG ko child actress bana dete. Similarly in immortal show Ruhi is not only more fun but also more samajhdar than leads ka bacha Abhir, parchai of his evil Dida.
Also, kids of leads bring them closer to each other like Savi, Kairav and even Abhir , new legacy kid of immortal show(who is bringing Abhi and Akshu closer) and Vinayak but this kid CA has been a huge source of drama in Maan's life (although it's not her fault). She has never brought them closer or rather, the poor kid failed. She has never had a close bond or connection with OG Anupama except sharing half a name and being pseudo mother-daughter. How can such a character who has rarely been a source of joy to leads or the viewers be a next gen lead? Only Maan bio kid can settle Maa's priority towards Anuj. Also imagine Maa being pregnant. She would be over the moon with the idea of being pregnant and becoming a great MAA again. Anuj would finally have a pyaar ki nishani with his meri Anu because Meri Anu loves bio kids. MD ka ansh badh jayega and finally Maa would care for Anuj . Pakhi and Toshu would actually see this kid as sibling unlike CA. Even when P warmed up to CA, she always saw herself, Samar and Toshu as one unit. Now a Maan Kid would join the unit. Dimpy and Kavya would welcome her with loving arms. Dukhmukh will fake his happiness. Kinjal, Adhik, Barkha, Baa and Vanraj will drown in their DDP together. Like true bio kid of leads, this kid will keep Maan together just like the way AnuRaj kids have bound AnuRaj in this nameless rishta.
Besides no matter how many kids Anupama produces, Shah kids Pakhi,Toshu and their spouses will keep creating troubles in a circular fashion and Anupama will have to run to resolve it kyonki woh sabki Maa hai ne... Moreover, they are young and there is no need for them to stop at one kid. So there can be more pregnancies where Anupama's expertise would be required.... So what will the biological kid do... Kharcha badhega as Anuj will have to keep a nanny for two kids since he is also busy giving services to his lady love and Shahs... Its all upto writers, they can write a track for adopted kid too.. I agree they never built up Anupama - Anu track.. Even when she returned after so much drama by CA, all she did was lipsync on 80s song. No conversation was shown. Nothing.. This was when we were told that CA badly needed Anupama after Maaya's death.... In Anuj - CA's case, they at least talk, whatever little is shown, the writing has put in some effort to make them connect. In Anupama - CA case, it feels like whenever social media puts pressure on writers about Anupama not being caring towards CA, they put in some random scene where we are 'told' that Anupama despite being always caught up with SH jimmedaris, is equally jimmedaar towards CA.. We are 'TOLD' never 'SHOWN'... No matter what you tell ur viewers, what u show will always be believed and make an impact...

the track would be a big time fail,that's why they didn't show it in the first place & went with this adopted child thing,which is also a big time fail but still
, god the very thought that she is going to be the lead after leap makes me cringe
