Can court exclude mother during minor’s testimony against father?

A father from Kolkata was physically assaulted during a visit to his 4.5-year-old child in a town four hours away. After being discharged from the hospital, he went to the police station, and his FIR was recorded. However, he was arrested in a POCSO case involving his own 4.5-year-old daughter. The child gave a tutored statement in court. After securing bail, the trial has now started. The child is now over 8 years old and, during weekly meetings with her father, is requesting that her mother not be present in the courtroom during her testimony. Can the advocate make such a prayer? How? The advocate is saying no. Note: The mother’s father is also an advocate in the same court.
