I m a mom. If my child had done what mishti did, (bathroom n pool ACCIDENT), I wud feel bad for Pari too. I too would show little love towards that child. Doesn't mean I don't care abt my child! Showing concern to others doesn't mean we don't love our child.
And pool scene was accident but bathroom was not. U expect Mauli to pamper mishti for that? Asking mishti to apologise was wrong? Mishti is going through difficult phase n till that is sorted out, they hv to see that she doesn't harm Pari knowingly or unknowingly. So little sternness was required.
She needs TLC no doubt.. but they actually need to make her understand more abt what's going on.. Make her understand that here Pari is not at all at fault.. Kunal mishti talks are required.
