Ishita abandoned Pihu. She left a new born baby and no reason can ever justify it. Maybe it was because of her own guilt for losing Ruhi or the terrible things Raman said to her, but it won't change the fact that she ran away without giving two hoots about her daughter. She never bothered to check on her daughter for seven years! And yet she is being portrayed as the only good mother on this damn planet!! Maybe she is a good mother to Ruhi and Aadi but to Pihu, m sorry but she is not. So CVs better stop trying to shove this non existant relationship of Pihu with Ishita down our throats. Just because Pihu is Ishita's biological daughter, doesn't mean that they need to share a 'special bond'. They have hinted towards this bond in the previous episodes and in the coming episodes m sure Pihu's Ishima jaap will be in full flow.
This is totally going against the concept of the show, that a stepmom can be a better mother than the real mom. It has suddenly become all about Ishita's great parenting skills and how everyone from ruhi to aaliya to pihu should want her and only her as their mom. This Shagun lady had no reason for turning negative now. They could have shown her getting married to Mani and Pihu willingly going to her. But NO. Now madam is negative, so poor pihu will go back to everybody's maa Ishima. Why can't Shagun be positive and have Pihu? Infact why can't negative Shagun have Pihu? She loves Pihu and is doing everything just to be with her daughter. Just like Ishita ran away with Ruhi once to keep her with herself.
