I do agree with many of you about sudden change in Babitas behavior..but I see it differently
Well from the very beginning Babita has always been very clear about not trying to get any monetary gifts from anyone ( Be it about money for business, Minnie education, collateral from Naimbee,etc). She is atleast now okay with all affection HS has for Minnie and she respects that. Even during the track where she takes him with her for Minnie, she took him along as she very well understood the care HS has for Minnie.
But about his gift which is VERY EXPENSIVE ONE (cameras are expensive and even Minnie mentioned that in yesterday's episode) Babita both as a mother and as a person is bound to draw a line between Minnie and HS. Even when they were really short of money (HS kept money in Minnie's jeans) she refrained from asking money from HS even when he offered help,so I don't see this as a drastic change in her character potrayal. Don't our parents tell us not to accept very expensive gifts from evem close relatives as howuch ever we decline there always has to be a limit in materialistic things atleast. Also Babita as a mother has to teach this to Minnie.
Yes I do agree HS gift is out of pure love and care for Minnie but again after his proposal Babita has to set a line again. She has never stopped HS in his emotional support for Minnie (exceptvin that jealousy track after which she understood) but again about materialistic things it is always considered to be parents arena. And B for a fact realizes that maybe HS is trying to get into father's shoes for Minnie which is not really easy to accept so fast when he has already proposed to her indirectly ,so she has to make sure he does not hurt himself too.Yes she was a bit loud though in expressing things which is may be because of her fears for now relating to HS.
