Filmmaker Sajid Nadiadwala's 3-year-old son has already done cameo roles in three films. Now he wants to bring him up strictly but his wife keeps spoiling him. Sajid says, "We have decided to put a stop to this, as I want him to concentrate on his studies. He's the 'Raja Babu' and my wife is akin to Aruna Irani who keeps spoiling her son."
