In Jain Dharma, a child diksha is a sacred and highly respectful ceremony. Filming the child while bathing or changing clothes is generally not उचित because it can disturb maryada, sharma, and privacy.

If any recording is done, it should be:

• only for necessary ceremonial documentation,
• with full consent of guardians and organizers,
• and without showing private or intimate moments.

So, the respectful Jain approach is: do not film the bath or changing process.
