As we all know PV tries to embed a social message in their storyline. It will be interesting to see if they can twist Ishita's track and shed some light on postpartum depression for Aarti.
I know a couple of them, who had this problem and took them an year or more to getover it.
Women suffer from postpartum depression - often triggered by any stress right after delivery. This causes the mother to experience frequent crying, loss of appetite, and trouble sleeping, over proctectiveness of the baby or completely ignore it. Its a very common issue now-a-days and awareness needs to be created.
The mother can be cured with the help of support, love and guidance from the family. Sometimes meds are also required to calm them.
I am speaking from personal experience, and this would make a great storyline now.
