Namaskar. In Digambar Jain tradition there isn’t a single universal “Sua rules” that applies to every newborn or every family. What matters most are the core Jain principles (ahimsa, satya, asteya, brahmacharya, aparigraha) and the local family/temple customs.

What you can do:

• You and your family can follow the general Jain rites for a newborn, such as the naming ceremony (Namkaran) and initial blessings, as practiced in your community. These are typically guided by elders, your guru, or the temple’s priests.
• Align any rites with Digambar practice if your family follows a specific Digambar setup (there are variations between centers). It’s best to ask your local Digambar Jain guru or temple priest for the exact sequence and timings.
• Emphasize daily Jain discipline for the child as they grow: ahimsa in thought, word, and deed; respect for all living beings; and a simple, truthful lifestyle suitable to their age.

If you can clarify what you mean by “Sua rules” (for example, a particular local custom, a name of a ceremony, or a specific community practice), I can give a more precise answer within the Digambar framework.
