Nimboli is born and brought in uneducated family where elders where not educated old fashioned, so for nimboli education is not that important. now also she is going to school but not because she values education . nimboli mentality is backward only.
Anandi thinks with education her mentality will change her attitude will change but the fact is nimboli and shivam both r normal human being, not great soul like Anandi.
So to change there attitude they should come to know that both r real sister and brother.
Anandi will get back her daughter only when she will reveal the truth. otherwise nimboli is not going to like anandi over managala.
Anandi is expecting too much from nimboli as well as shivam.
