As you rightly said, it is like the first child syndrome only. When you have pampered your first child for long years ( 3-7) as the sole attraction of your attention and love, all of a sudden you dump the child for your second child and shower all you love on that, the first child will ultimately feel jealous of the second child though it is not the second childs mistake. The first child will end up hurt the second child in the absence of the parents and will play innocent. If you don't prepare the childs mind to welcome the forthcoming child, the result willbe disaster. The child might grow agrressive or go introvert.Just imagine while a mother expecting her second child, either th efather or mother keeps teasing the child or provoking the child in the name of coming child how will the first child develop the feelings for the second child or t be more precise if the mother was not ready for the second child (content with the first) and by force from family plan forthe second, she will start filling the childs mind with all her hatred for the second child least she would have thought that everything was recorded in the childs mind non-erasable disk and as the pregnancy grows, teh mother will start feeling for her second child as well and expect the first child to accept the new comer open heartedly.Jalal did the same thing with Ruqu. He made her the competiter of Jodha by provoking her to take up Chess game to humiliate Jodha, He gave mansabdari to Jodha's brothers and claimed that he did it to watch them bow to him (when Ruqu asked for the reason), he had told her he had married Jodha to avenge his revenge on Jodha. So what do we expect Ruqaiya to feel than what she feels now, betreyed by her husband / friend who is going back on his promises.Had he told her that he married jodha as he was attracted to her ( in the initial days only), she would ahve come to terms with that only. She share a cordiel relationship with Salima Begum and that is teh example that she can still care and respect people.
