OK so it depends on the no. of days ishveer are going on vacation... I mean if it is a short 3-4 day one then they can leave Raagini at home but if on a long one like 1 week or more...then they should take Raagini...As according to the story Raagini can't stay away from either of her parents for soo long as she loves them a lot...Although I will suggest leaving Raagini so that the can get a little bit of time for each other after so looongg... So now it depends on you...Love you...
