I think its got to do with the fact also that they got separated when they were very young too. Like for example, i initially felt that about Aamir too..because he does not talk about his older kids, but then realised he is self obsessed and tends to spend more time with azad more because they live together. But Aamir is mostly honest and admitted he did not spend as much time with his older kids but is satisfied of their relationship because they are close to him and are like friends to him than kids. Also, the al jazira vedio has junaid,ira and kiran playing Catan because they wanted a family snapshot and he included them than just azad.
Major difference between these two divorced couples is that, the mother( Reena) remains part of the family, so the kids get the emotional security that despite their parents are separated, they come together on occasions and the step mother is also at peace and hence they grow up in harmony.
Just like Saif said, i wrote a note to Amrita before marrying Kareena acknowledging the time they spent together and sara had told him then that i will come with a more happy heart now.
