Bruce’s quote before giving the cradle a slight rock is “I don’t always get what I want.”
In Comics Bruce and Betty had been trying for years to have a child of their own but to no avail. After the Gamma accident Bruce feared the Hulk genes would be passed on if he ever tried to conceive.
So no, he will never have the child he wants. Or the chance he needs to prove that he would be nothing like the monster he was forced to call a Father.
