Puppies also stay with their mothers for 8 weeks. It's called Lucy's Law (U.K.). A home birth of a surrogate born baby can see the newborn handed over in 6 hours.
It is possible that she had fertility issues but I find it strange to say this is cultural. Chopra originates from India, land of Bollywood. This genre of film often depicts surrogacy stories and celebrates the practice.
India banned commercial surrogacy in 2019 and this is already being challenged under a woman's 'right' to grow, birth and rent their wombs and sell babies.
Chopra may have been in and out of clinics for the purposes of harvesting her eggs so she is genetically related to the child she paid another woman to have.
In India is it culturally sensitive to be known as a woman who is infertile but then it is culturally acceptable to buy a baby? Would she be well-thought of by her family to have been able to have got a baby and fulfilled her duty as a Indian daughter when she hasn't given birth but used her money instead?
Regardless she is a very wealthy famous Indian woman, married to a very wealthy famous man, who has subcontracted out the service of pregnancy and labour, with all the risks that entails and this is being celebrated in this article.
I'm sure she will wrap up filming soon, or maybe her husband can complete whatever project he is working on, and someone can go fetch the baby at their earliest opportunity.
27 weeks and no one there to love you but the woman who was paid to have you, if that's even true.
